If you are running Seagate Backup Exec 7.0, build 719, receiving Pop-up messages may block the CPU, causing applications and non-critical services to stop responding until the Pop-up is closed.

You really should switch to UltraBac.

Alternately, use Regedt32 to browse to:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager\SubSystems\Windows

During the install, Seagate modified the SharedSection=1024,3072 to SharedSection=1024,3072,512.

Unfortuneatly, they dropped the =16 from MaxRequestThreads=16. Put it back. In case you fumble finger, the entry should look like:

                              %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
Do not make this change on Small Business Server.
