Exchange FE OWA login issues

[Vitalix]

Hello,

We have a FE/BE setup with Exchange EE 2K3 SP1 on both machines (Opsys is

Win2K3 EE). The FE has SP1 for Windows 2003 server, the backend is just

Win2K3 server.

We have OWA working fairly well using forms authentication, however

periodically, about once every 6-10 logins, the login page will just sit

after clicking login. It will timeout in about 5 minutes. However, if during

that pausing period, the user hits F5 or refreshes the page, they instantly

go to their inbox!

We are presently using Vasco tokens to authenticate, but the issue happens

even when Vasco is turned off, using just AD logins.

Put a sniffer on, everything looks like it's communicating normally. The

pause happens with the owaauth.dll file. Happens periodically so tough to

nail down.

Anyone else have similar issues?

Thanks in advance as always!

I just recently had a similar problem when using form based authentication. I used method 2 and changed the logon.asp to include the default domain.

Another thing I would look into is to make sure that your security settings on the exchweb virtural directory and verify that the security permissions are anonymous access.

Hi Chili,

Exchweb is anonymous (at least in IIS on the FE). Are you referring to FE or BE, in ESM or on the IIS side?

I was refering to the side that you checked(IIS on the FE) did the link i sent you do anything? I would definately try method 2 (adding default domain to logon.asp)
