Hi,

Office environment, T1, 2 computers, both Windows XP Professional. First computer (desktop) has a printer installed. Second computer (laptop) shares the printer via network.


Getting an error on the desktop computer in Control Panel --> Administrative Tools -->Event Viewer -->System


Event ID 2011

"The server's configuration parameter "irpstacksize" is to small for the server to use a local device. Please increase the value of this parameter."


Systems hangs up, restart and so on - BIG inconvenience.

Please help. This is a very important machine, can't loose anything, afraid to modify registry manually.

Is there a work-around?

This is for NT so please do not proceed with any of it if you do not find the exact same items referenced here

Event ID: 2011
Source: SRV
Description: The server's configuration parameter "irpstacksize" is too small for the server to use a local device. Please increase the value of this parameter.

RESOLUTION

Warning
This workaround may make your computer or your network more vulnerable to attack by malicious users or by malicious software such as viruses. We do not recommend this workaround but are providing this information so that you can implement this workaround at your own discretion. Use this workaround at your own risk.

WARNING:
If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

You can increase the IRPStackSize value. You must first add this value to the following key if it is not already present:
HKEY_LOCAL_MACHINE SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters

Value Name: IRPStackSize
Data Type: DWORD
Default: 0x4
Maximum: 0xC

Increasing this value requires some memory from the non-allocated memory pool, but the impact should not be noticeable.

NOTE: It is not always advisable to set the IRPStackSize value to its maximum of 12. Generally, you should start the value at 4 and work your way up, increasing the value by 1 each time. The problem may still occur if the value is too high.

This error message may also occur after installing or uninstalling virus-scanning software. You may want to remove the virus-scanning software or increase the IRPStackSize if you need to use the software.

thanks, that is exactly why I don't want to do it manually, I know a few things, but registry is not my forte.

I happen to think that the initial upgrade from Win2000 to XP didn't go over too well, because for some reason, many server components are still present, even though the machine was never used as a server.

Did I mention that it's my bosses' computer? :tazz:

well, I would love nothing more than to reformat his PC, do a fresh XP install, SPs and all that, but when I start thinking about how much work it's going to take archiving, copying and burning existing data - I cringe.

Thank you again

95% of answers from Microsoft involve installing the latest service packs, possibly you would need to re-run the network set up after doing the updates

You can add whatever updates without re-installing XP

You have overlooked the wheeze aspect of being unable to work while the updates are downloading and installing

again, it's my bosses' PC who's an overworked workaholic and I can't do anything during normal business hours which are 7:30AM - 7PM, by then I just want to go home. According to my boss, his computer needs to be fast, reliable, never hang up, have no crashes at all, must be a stable, robust system - he's dreaming
