Hey Evan, A server w/ 4GB would have a theoretical maximum of 360 MB but with Terminal server enabled, it goes down to 160MB. The registry will put the amount of paged pool memory back to 328MB of paged pool memory. Resolution: Implement the following registry: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management "PoolUsageMaximum"=dword:00000030 "PagedPoolSize"=dword:ffffffff Restart Ark ________________________________ From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Evan Mann Sent: Tuesday, September 13, 2005 1:39 PM To: thin@xxxxxxxxxxxxx Subject: [THIN] Reduce size of default registry hive I have a 198meg default registry hive on a 2000 SP4 TS server.
