SYMPTOMS
If you use the Regserv32 utility on a Microsoft Windows 2000-based computer to manually unregister Fltrsnk1.dll, the Simple Mail Transfer Protocol (SMTP) message screener (SMTP Filter sink) does not delete the binding to the SMTP service. Also, the message screener module may continue to start with Inetinfo.exe after you unregister Fltrsnk1.dll by using the regsvr32 /u fltrsnk1.dll command.

Note that you can prevent Fltrsnk1.dll from starting if you delete or move the file. When you uninstall Internet Security and Acceleration (ISA) Server, Fltrsnk1.dll is deleted.



CAUSE
This issue is caused by a problem in the code that unregisters Fltrsnk1.dll.
