Hi,

Pretty much standard OWA publishing setup with ISA2k4. FBA auth, SSL bridging, 2 NIC ISA, ISA member of domain, FBA is disabled on FE.

All seems to work pretty much 100% until user sessions timeout. If users leave OWA open for more than the public computer timeout (22 mins I think) and then click on any item within OWA screen, they are told their session is timed out and they are prompted to relogon (as normal). However, once they enter their credentials they recieve a "Unknown Request. The request could not be resolved by the server." in a white window. If they close the browser and relogin, all works fine.

Has anyone else seen this???

Thanks!

Hi Jason,
i have the same problem, only i have this on my windows mobile phone.
also what do you see in your monitoring logs?
Original Client IP Client Agent Authenticated Client Service Server Name Referring Server Destination Host Name Transport MIME Type Object Source Source Proxy Destination Proxy Bidirectional Client Host Name Filter Information Network Interface Raw IP Header Raw Payload Source Port Processing Time Bytes Sent Bytes Received Result Code HTTP Status Code Cache Information Error Information Log Record Type Log Time Destination IP Destination Port Protocol Action Rule Client IP Client Username URL Source Network Destination Network HTTP Method

I think this API filter might mess things up....

Hi,
Here's my setup:
Firewall appliance (Watchguard) that forwards https requests to the ISA server external NIC. ISA 2004 running on a Windows Server 2003 Standard server with two NICS, one with an "external" address (by that I mean in the same address sapce as the inside NIC of the Watchguard). The other NIC is in the same address space as the other machines on the LAN. I have DNS running on this machine also.

Exchange is running on a Windows server 2003 SBS machine.

I have followed the article to the letter. I can get to the FBA screen from the browser on the ISA server, but when I try to access it from any machine outside of the LAN I get a "page cannot be displayed" Error code: 404 page not found.

Here's what I know is happening: The outside client is getting forwarded to the ISA server, because the Security Alert pops up, I press the yes button to proceed, then the "page cannot be displayed" error occurs.

What did I do wrong? [Frown]
