Authentication Failed on 7.0 Midtier

[Kaiser Norm E CIV USAF 96 CG/SCWOE]

** Hi everyone:   Can someone tell me what I'm missing? We have 7.0 loaded up on a test server-server and midtier on the same box.  The server is running great, and we have the miditier seemingly installed correctly (config page comes up fine).  When we attempt to pull up a form, we get the logon page correctly, but when we supply the Demo username and password (we set a password), we keep getting Authentication Failed ARRERR 623.   Anyone have any ideas on what I'm missing...seems to be something simple.   Norm __20060125_______________________This posting was submitted with HTML in it___
