I have a laptop running Windows XP, Service Pack 3. I usually only use Firefox or IE and every few days I will get the above error message when i try opening any other application, including these internet browsers. These are the only applications running at the time I get this message. I can't access task manager or shut it down properly, the only possible way to get things to work again is to hold down the power button until it shuts off and then start it up again.1 person needs an answerI do too

Are you running Trend Micro antivirus? If so this is a known issue. Either way here are some resources that you may try to overcome the problem. Please use these possible solutions at your own risk as there are some registry changed involved which can kill your system if not done properly. Also, you may just need more memory (RAM). From a command prompt execute the following command and reboot: net config /autodisconnect:-1 1 Solution #2: Enlarge paged pool - reboot required HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management Value: PagedPoolSize Data: 0xFFFFFFFF Solution #3 To resolve the issue, increase the IRPStackSize value in the registry: 1. Open the Registry Editor: a. From the desktop, click Start > Run. b. Type "regedit" then click OK. Important: Always create a backup before modifying the registry. Incorrect registry changes may cause serious issues. Should this occur, restore it by referring to the "Restoring the Registry" Help topic in Regedit.exe or the "Restoring a Registry Key" Help topic in Regedt32.exe. 2. Go to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanServer\Parameters. 3. In the right pane, double-click IRPStackSize. Note: If IRPStackSize does not exist, create it by doing the following: a. Right-click on the right pane and then click New > DWORD Value. b. Type "IRPStackSize" exactly as it is shown here and then press Enter. 4. For the Base section, choose the option Decimal. 5. In the Value data field, type a value higher than the existing value and then click OK. It is recommended that you increase the existing value by 3. 6. Close the Registry Editor. 7. Restart the computer. If the issue persists, increase the IRPStackSize value again or set it to 20. See also: http://support.microsoft.com/kb/909095
