Hopefully someone has run into this problem before and has a fix. I
apologize if it's already been posted, but I've searched everywhere and
was unable to find anything relevant.

I have a few remote sites that only use the Zfd client to login to the
middle tier server. They don't need the full client, we only need to be
able to conduct remote management and DLU. It works great for a few days,
but then the Zen login screen just disappears, and is replaced by the
Microsoft one. The registry still contains nwgina.dll in the winlogon

Has anyone seen this before, if so, do you know of any fixes? It's
happening on XPsp2 machines, with the latest Zen client. Thanks for any
