This definitely appears to be my issue. There is a sub key in the one mentioned below and it has 10's of thousands of mappings in there. ________________________________ From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Ark Opara (VMC Consulting Corporation) Sent: Tuesday, September 13, 2005 4:17 PM To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: Reduce size of default registry hive From what I can tell there is a fix for this issue but it does not appear that the KB has been published yet. Here is a workaround for this issue, if you want the hotfix you would have to call MS and ask for hotfix 906952, the default user hive in %systemroot%\system32\config may become excessive in size ( > 5Mb) due to registry values not being removed upon logoff in HKEY_USERS\.default\printers. The values will have the following format '\\%ClientName%\%PrinterName% (from %ClientName%) in session x,localspl' ________________________________ From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of M Sent: Tuesday, September 13, 2005 3:40 PM To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: Reduce size of default registry hive OK I was going to mention an age old issue where the registry would increase with entries that contained users temp folder and they were never purged. This was running Office 97 or Office 2000 and using forms. HKEY_CLASSES_ROOT\CLSID would be full of entries. I would definately agree with Bruce and his observations. The other thing would be to allow the servers to get to a certain point and then rather than wasting time blow them away and redeploy using with an up to date Ghost Image or Scripted build.

These servers only have 2 gigs of RAM, so I guess that's the most they can get. The key seems to be reducing the default key... somehow ________________________________ From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Ark Opara (VMC Consulting Corporation) Sent: Tuesday, September 13, 2005 3:02 PM To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: Reduce size of default registry hive 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. Is there some effective way to greatly reduce this? I'm having major issues getting users logged in because of registry size keeps bumping up against the maximum
