We are running WinNT 4.0 on LAN network. Just recently, clients have been receiving user32.dll errors. They pop up sporadically, but frequently. We received 8 yesterday??? Any help would be apprieciated.

This is from TECHNET Q142676. This reg hack has fixed errors with screen savers causing the crash and with many apps being open at once (i.e. multiple schedules. Although it mentions servers I've used with success on workstations only. Good Luck SYMPTOMS ======== When you try to start a service a pop-up dialog box appears with the following message: - DLL initialization failure Initialization of the dynamic link library c:\windows\system32\user32.dll failed. The process is terminating abnormally. CAUSE ===== The system has run out of memory to create a new desktop heap for the service being started. RESOLUTION ========== Fixing this problem requires editing of the Registry and restarting the computer concerned. WARNING: Using Registry Editor incorrectly can cause serious, system-wide problems that may require you to reinstall Windows NT to correct them. Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk. 1. Run the Registry Editor(Regedt32.exe). 2. Under the HKEY_LOCAL_MACHINE subtree, go to the following subkey: \System\CurrentControlSet\Control\Session Manager\ SubSystems\Windows The default data for this value will look something like the following (all on one line): %SystemRoot%\system32\csrss.exe ObjectDirectory=\Windows SharedSection=1024,3072 Windows=On SubSystemType=Windows ServerDll=basesrv,1 ServerDll=winsrv:UserServerDllInitialization,3 ServerDll=winsrv:ConServerDllInitialization,2 ProfileControl=Off MaxRequestThreads=16 You will need to make the following change to this value: Scan along the line until you reach the part that defines the SharedSection values and add ",512" after the second number (without quotes). This value should now look something like the following: %SystemRoot%\system32\csrss.exe ObjectDirectory=\Windows SharedSection=1024,3072,512 Windows=On SubSystemType=Windows ServerDll=basesrv,1 ServerDll=winsrv:UserServerDllInitialization,3 ServerDll=winsrv:ConServerDllInitialization,2 ProfileControl=Off MaxRequestThreads=16 After making this change, close Regedt32 and restart the server. This change will limit the size of desktop heaps created by noninteractive services to 512 KB, which should be ample for most services.

We have made this change to all of our servers but this continues to happen. At times, over 45 User32.dll error message processes are running. Are there any additional fixes? It is believed that we do not see the error until Placeware Server is loaded (www.placeware.com). Any suggestions would be greatly appreciated.
