JSI Tip 7657. Users receive 'Unable to change password on this account (C00000BE)' from a Windows Server 2003 domain controller?

Windows Server 2003 supports 1024 sessions to pipe\samr that use different security contexts, whereas Windows 2000 supported 2048 sessions. When the limit is exceeded, the server returns a STATUS_INSUFFICIENT_RESOURCES error.

Normally, a pipe is only open for a short duration, but if the client doesn't send a close request, you may reach this limit.

To workaround this behavior, you can close the open open sessions by running, or scheduling, the following batch:

@echo off
for /f "Tokens=1" %%f in ('net files ^| findstr /i /l /c:pipe\samr') do @net file %%f /close
