temuskoff Posted June 21, 2006 Report Share Posted June 21, 2006 I installed Retrospect Single Server v6.5 on Windows NT 4.0. The install went fine, and Retrospect worked perfectly. However, a little testing revealed that users could no longer logon to the Windows domain due to not being able to access files (Event ID 2011 in the Windows event log.) A typical Windows error message includes the words: Not enough server storage is available to process this command. Further research indicated that this problem is typically caused by Symantec products which change the registry value for IRPStackSize to a small number. Checking my registry at [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters] I found that IRPStackSize was set to a value of 6. I read that the maximum allowed value for Windows NT 4.0 is 12, so I changed the value to 10 (decimal) and rebooted. Success!! Users are now able to logon. So, my question is this: Does Retrospect change this value during installation? Why would it do that? It must make the change, as I made absolutely no other changes during this time period. In any case, hopefully this posting will help future users with this problem. Link to comment Share on other sites More sharing options...
