The system has reached the maximum size allowed for the system part of the registry. Additional storage requests will be ignored.

I am getting this message on my thin-client server, and the OS is windows 2003 enterprise edition. Even users are getting the error messages( ).

  1. Check the sizes of the registry hives in:
    • C:\windows\system32\config

Security __ MB

Software __ MB

System __ MB

Default __ MB

  • C:\Documents and Settings

Default User __ MB

LocalService __ MB

NetworkService __ MB

User Profiles __

Each individual User Profile sizes __ MB (Sometimes the median and biggest size can be enough).

2. Make sure that you don’t have the following registry key set:   HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\RegistrySizeLimit

3. If you don’t have the registry key set, install the latest UPHClean (2.0) in, set the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UPHClean\Parameters\SHARING_VIOLATION_REMAP (dword) 1 (hex), then stop and restart the UPHClean Service
