Excellent fix! Thanks.
This error occured after installing Acronis True Image Home 2010.
I set the value to 20 and I am able to share the pc on my network again.
Good work.

I have three xp computers on my network. All have Acronis & Norton installed. I keyed in the above(abbreviated message) when I could not share on one of the computers.

I had to expand the stack to 22, but it worked very well. I am impressed by this site.

You guys rock! This error just started popping up after 2 yrs of hassle free file sharing between XP Pro and Vista.

Uninstalling was not an appealing solution. I tried just adding the registry key IRPStackSize (mine didnt exist at all, let alone have a value, i set mine to 22 since that seemed to work for a poster using a similar set up to mine) and rebooted "Machine B".

Went back downstairs to Machine A and entered my path \\MachineB\blahblah and it connected in a snap. Just like the good old days.

So looks like I got it solved without uninstalling anything.... so far :)

I am now making a donation because this was the fastest resolution to any Winblows problem like this - and there have been tons - EVER!

Thanks again.

That was definitely the culprit. Installed it Friday to clone my drive and "not enough storage." Added the IRPStackSize DWORD 0x0000000f (16) parameter and its all working again. Thanks.

I have 4 computers in my home network. All use XP, the one I call "the server" is tied to our large format printer, and serves as a print server, and backup storage. I recently upgraded the size of the hard drive and used Acronis to clone the new drive. It wasn't until I needed to move some files to the USB external drive attached to "the server" did I notice that I could see "the server" from every other computer, but could not get onto any drive, and would get the error "not enough storage space"... I tried everything, then I found this page, late last night. I had to wait till I got home from work this evening, but all I did was to remove Acronis, and VIOLA' everything worked fine again. I did not have to edit the registery....thank goodness for this site... My advice to Acronis users is to install, use, and remove.

Acronis TrueImage & 16 is the go.
Thanks!

Didn't realise that Stack Sizes were an issue any longer. Used to set them back in the dream time but have thought nothing about them until now.

Norton will never be an issue with me for problems. Will not even look at a computer, let alone touch it if I so much as hear that N word.

This tip worked for me. The most important part of the tip is that the problem is on the computer where the share is. For me the IRPStackSize on this computer was already set to 18. I changed the 18 to 22 and was able to share all folders.

I have had three computers networked (Ethernet) for the last six years (different machines at different times) one with Win98 and all the others with WinXP (various SPs). NEVER saw this problem before now. However, I started using Acronis last year in the Seagate version and then (foolishly) purchased the full Acronis version and then upgraded that. I recently installed the Acronis product on my newest machine after which my sharing problems began. This is what made the tip so valuable - who would have guessed that the old computer was where the parameter needed to be changed! This seems to be fixed FOR NOW. But judging from my experience (18 did not work) and from some of the later posts, there is likely more going on here. I sure would like to find a less troublesome replacement for Acronis for imaging though. Have you ever noticed how many processes and registry entries Acronis puts on a machine?

P.S. At the same time I am wrestling with the sharing problem, I noticed that on my new powerful Workstation (with very little software yet installed) that I started getting freezes sometimes when I tried to clear the Taskbar Start Menu. Instead of clearing in a few seconds (at most), it was taking up to three MINUTES and sometimes required halting Explorer to clear. This weird behavior also began with the installation of Acronis. The system is still sick and I plan to uninstall Acronis (if one can get a clean uninstall with this product) and see if this improves the Start Menu clearing problem.

Thanks. It worked for me. I placed a decimal value of 25 in Vista (as the server), and XP Prof is the connecting client.
I only experienced this problem after installing Norton Internet Security 2009 yesterday.
The day before installing Norton, I was focusing on this error "the server cannot perform the requested operation" in the same XP machine, I installed LLTD in XP client and still observing, but it seems to be working now coz I haven't received that error "the server cannot perform..." yet as it was replaced by the error "not enough server storage." :-)

Hey guys, thanks everyone for useful comments. I did finally manage to solve this server strorage problem. From my Windows 7 machine I was trying to map the network share on my Windows XP machine. I have Acronis True Image (which I passionately love!!!) installed on both machines. I was playing around with this IRPStackSize entry on my Windows 7 machine and it just would not work. I started by 15 and went as high as 50. No chance!

When I almost committed suicide of frustration that I would have to remove the True Image, it just came across my mind that maybe I was fixing the wrong side. I did indeed!!! As soon as I set the IRPStackSize parameter to 18 on my Windows XP machine, I could map the network share. Wow! Thanks a lot for this discussion!!!

After fiddling around with the IRPStackSize setting many, many times to no avail, I found a hint in a posting about Acronis. I opened SeagateDiskWizard and ah ha! "powered by Acronis". I uninstalled SeagateDiskWizzard and now I can get to the shared folders on my laptop. I have IRPStackSize set to 50. I think I'll go lower it to something more reasonable.

I added the IRPStackSize several weeks ago when this problem first started to apppear. The network has run great since until today. After the server recieved an automatic update from MS the problem appeared again. I tried to increase the stack size but when I entered regedt32 the server reported back with "Insufficient resources to complete the requested service". Any thoughts

Thank you so much! I have spent hours trying to solve this. Who would have thought ....?

On my network I have 2 PCs - here are the specs:
1. PIII866, 512 ram, 80G HDD, Windows 98
2. Celeron 1.8, 768 ram, 1x40G + 1x200G HDD, XP SP3.
ZoneAlarm too, so I suspected it first :-( .

Suddenly from the W98 m/c I was unable to access the XP one, which I'd done often before. Explorer showed the XP one, I was able to expand the entry to see its partitions, but when I tried to expand further this message appeared:

\\Amethyst\backup2(m) is not accessible
Not enough memory is available. Quit some programs.

I won't go into everything I tried, but it was all on the W98 machine as I thought the fault lay there. Never thought of the XP one as it could see the other just fine.

I realised I had just upgraded Acronis TrueImage from 9 to 11. I uninstalled it, and now everything works just fine. When I have some spare time I will try juggling Acronis and ISPStackSize [correction: IRPStackSize] to get them both working. I will also contact Acronis (more spare time?).

Joined to thank you and vote you all the stars: I will donate, and return to the site in the future.

I was VERY close to just throwing in the towel and re-formatting, but stumbled upon this site and this thread. My problems started when I used this PC to clone a laptop hard drive with Acronis. It cloned the drive great and I had a perfect back up of my laptop to keep in a safe place. I tried all kinds of different values for the IRPStackSize and nothing seemed to work. Turns out just un-installing Acronis did the trick for me. Its 2am now so i'm off to bed..... but wanted to say thanks first...

Thanks!!!!!!!!!

I had the problem but when I looked in the registry at the noted location I couldn't find ANY such line (IRPStackSize DWORD 0x0000000f (15) )
So I crossed my fingers, then uncrossed them (I can't type with my fingers crossed)
and added IRPStackSize DWORD 0x0000000f (15) as a new DWORD item.
That solved the problem. The network had worked in the past and I have no idea how that line got removed.

Thanks for helping with this.

Mike

Thanks for the great help. Ran into this problem before on another setup. This time it was access to a computer running XP PRO from a computer running Win2K PRO. Had to define IRPStackSize and set it to 15 on the Win2K.

Help.
I'm in a windows vista bussines, with the problem 'Not enough server storage is available to process this command' when i try to install windows vista compatibility with server 2003:

http://www.microsoft.com/downloads/details.aspx?FamilyID=9bf2f1e4-1b2c-4...

I tried to increase the IRPStackSize from 15 to 50, and don't works.

Please i need a solution for my work. Pleaseeeeeeee :(

Have a longstanding home network with various laptops for family members and never a problem running network wizard, enabling sharing, saying WORKGROUP, sharing a folder, and so on. After a new hard drive on our T61, and reinstalling XP from the IBM disks, coldn't connect due to the error ""not enough server storage is available to process this command". XP3 on all machines. There may have been Norton software and I would have uninstalled it as I use ESET Nod32 with no problem. Ran the Norton uninstall program anyway but that didn't fix it. Edited the registry to a value of 21, but it then says 33. It should say IRPStackSize Reg_DWORD 0x00000015 (21) or should it be 21 (33)?

Also, my the T61 has a DWORD value for "size" but none for IRPStackSize, whereas my new T400 has IRPStacksize but no Size. Any idea of the distinction?

I rebooted both computers and this doesn't fix the problem with it saying 21 (33) and 15(21) and neither works. Oh, ok, I see, it should have a DECIMAL value of 21. You have to click decimal rather than hexidedimal when editing with regedit. Still, that didn't work.

However, FROM that computer the T61, i can reach the other computer, so not to worry.

Mike - informed user is all

Hi, this has not worked for me. First of all I have 64bit vista and not 32bit vista. When I go to the dword next to it It says that dword is for 32bit vista. Then under that it has a qword which says for 64bit vista. So I choose the qword instead of the dword but not only am I not able to type in IRPStackSize but I'm not able to do it under qword either. Now admin when you made this topic, it was 2007, which I'm sure 64bit vista was not out by then. But what advice do you give for 64bit users who is unable to download the windows installer because of low storage. What's the advice for 64bit users to get us out of this mess? Please help me admin I really need to download this windows installer 3.1. Thanks

Hamachi file sharing, free version never did work for me until I created that registry key and set it to 17.
Now it does work.

Just a note:

I added an RPStackSize of 25 to A WinXP Sp2 x64 system and it worked.

Thank you.

My laptop can now finally see my desktop files after probably more than one year of this particular problem! (My testing is somewhat ongoing, and I have not yet checked the other computers in my home network.)

My desktop system has the SP2 XP Pro OS. Partitions "C" and "D" are on the boot HD whereas partition E is on a second HD.

A value of "16" (on the desktop system) for IRPStackSize was not effective. A value of "18" had the strange effect of making the sharing possible on the "E" partition, but not on the "C" or "D" partitions! A value of "21" succeeded in making all three partitions visible. The items that are peculiar to "E" is its location on a separate hard drive (on a separate HD controller) and the fact that its drive letter was re-assigned to "E" to work into my partitioning scheme.

Thank you for this solution! I wish that I had found it a year earlier.

PS: I have had several versions of Norton AV on this system and currently have Norton AV installed. I am in the process of migrating away from this program.

Having wrestled with this problem for years and given up, I encountered it again recently whilst installing a new PC and laptop, which I need to sync with each other, so I had to try again.

Changing the IRPStackSize to 16 did the trick, and I changed it back to 15 just to check. Sure enough it didn't work.

Thanks for providing the solution to this very irritating problem. Could someone tell Microsoft?

Thanks! The registry tweak works well.

I have a home fileserver with a lot of internal drives and partitions as well as an external hard drive enclosure connected to the server via USB and a USB printer. Other computers could see the description and drive letter for the external USB drive, but got the "Not enough server storage..." error message when trying to access any of the files stored on it.

I checked the registry and the key wasn't there. So I entered it and set a decimal value of (16). I separately tried restarting the Server service, logging out of and back into windows, and rebooting, all to no avail.

I cruised the nearby keys and noticed that there were 16 shares listed. Not sure that it matters, but it made me think that a higher number would be better for the stack size.

So I tried the suggested value of decimal (25). After I made the change, all it took to get everything working again was a restart of the Server service via Administrative Tools.

Thanks again!

hi,

I finally got it fixed for my external usb drive, after seeing it for a few (2-3 days, but never before that) but it could have been resolved by either of two things

- i played around with the different values for the stacksize, but nothing helped, but i didn't reboot each time, but restarted the services, only the last time (see below) i rebooted, so it could be that a reboot was necessary and the value 25 helped.

- i completely forgot it, but a spontaneous occurring vprorecovery.ini on the external drive after a convert/format to ntfs (from fat32, even tried that) helped me to remember that i had a trial version of norton (yes norton again!) ghost which accidentally expired a few days ago. Removing and rebooting resolved it.

... but I can't be sure what did the trick, but the expiring norton around the time that the issue started is too much of a coincidence in my humble opinion.

regards,

Peter

Thanks for providing this solution . I had this when trying to map a drive on my XP Pro desktop from my Vista Notebook . In my case i could map any share on the XP box ( 10 drives up to 400G in size) except one which gave me this error . This drive was a USB ext 750G HDD . Applying the registry change with a value of 16 and restarting the server service fixed the problem .

XP box has Norton 360 and trial of Acronis True Image Home 2009 but i can't say that either "broke" the sharing as I hadn't mapped this USB drive before they were installed . I had mapped other drives before and they were all unaffected .

I thought this might be significant but I don't know how .

Thanks guys for all your helpful post. But how do I resolve this error in the event that I cannot even logon to the server. I am completely shut out of the server.

On system logon to Window Server 2003. I get this error.
System cannot log you on due to the following error Not enough storage is available to process this command.

I had a call from a user today having this exact issue. I noticed the entry was not in the registry and I thought I was in for a quick fix once I read the solution. I added the registry entry and experimented with different values and still nothing. After banging my head on the desk for about 15 mins. I figured if all else fails blame Norton. I did an uninstall of Norton Anti-Virus 2009 with the Norton Product Removal Tool.... and like magic, all of the mappings were working again with no issue.

I recommend for those who aren’t having success with the registry fix alone to try to uninstall the protection software as a troubleshooting step... worked for me. The user is now happy with AVG and everything is working as intended!
