Verify correct version of IMAsystem.dll
After installing Service Pack 1 for MetaFrame XP and rebooting, the server returns the error message: "Entry point cannot be found."
In the event view, the following message appears.
Event id: 26
Source: Application Popup
Desc: Application popup: termsrv.exe - Entry point not found. The procedure entry point IMA_BUF_EventBuffer2 @@QAE@GABVIMAVERSION@@K@Z could not be located in the dynamic link library ImaSystem.dll
Resolution
The resolution to this issue is in Citrix Knowledgebase article CTX836242 (Below.

CE). While the DLLs listed in the article are different, you can apply the process described in CTX836242 to resolve this issue. Essentially, under certain circumstances, IMAsystem.dll is not being properly replaced in the System32 directory by the Service Pack 1 installation. Manually deleting the old Imasystem.dll and replacing it with the Service Pack 1 DLL resolves the issue.

Users cannot log in after installing MetaFrame XP Service Pack 1.
After installing MetaFrame XP 1.0 Service Pack 1, the following error message(s) may be displayed:
"ERROR: Uninstall could not remove the Feature Release settings of this server from the data store. Uninstall will now exit." when attempting to uninstall the service pack.
- or -
"net.exe- entry point not found-the entry point ima_getprinterflag cannot be located in dll imamfrpc_client.dll" occurs when logging on to the MetaFrame server after uninstallation of Service Pack 1 fails.
These issues happen because the following three DLLs are not being replaced:
ImaRPCClient.dll
ImaMfRpc_Client.dll
ImaLicRpcClient.dll
These files have dates before 12/2000 unless hotfixes were installed. There may also be instances of each of these files being marked for deletion.
To resolve this issue:
Manually delete the files that are marked for deletion.
Rename the three original files and replace them with the updated ones from the SP1/FR1 CD or download.
Reboot the server.
