hmmm, there a lot of bugs when using the NT database mode. We don't really have anyone testing out the NT side of it.
In pop_lock.asp find all instances of the following code:mLev = cint(ChkUser2(Request.Form("user"), Request.Form("Pass")))
to this:mLev = cint(ChkUser2(strDBNTFUserName, Request.Form("Pass")))
It should appear 4 times in the file. This should be reported as a bug.
