Recently needed to update one of our IIS applications to use ASP.NET 4. The application had some issues with dropping out and not being accessible. It would seem that I have that issue resolved, but now when a user tries to access OWA, they get the above error.

The application added was Sage Accounting, and was added to the IIS DefaultAppPool, and required ASP.NET 4.

Since changing the ASP.NET setting to use v4, it appears that both local and external access to OWA gets the error. Changing back to ver 2.0 does not correct the issue.

I've checked all the configuration and variations I can think of, and while the EWS (Timesheet) application is stable, we are unable to access OWA.

Any thoughts?

Could try resetting the virtual directories...

I have reset the virtual directories - twice. Twice because I missed a step in deleting the actual directories and of course had to restart. Would it make sense to try again?

I'm assuming you have the DNS on the SBS pointing to itself as the primary DNS server, correct? If not, please do this.

Secondly, can you check the bindings in IIS the default website should have both 80 and 443

]Secondly, can you check the bindings in IIS the default website should have both 80 and 443

Yes - IIS Default Web is bound to 80 and 443.

I'm assuming you have the DNS on the SBS pointing to itself as the primary DNS server, correct? If not, please do this.

Yes, it is pointed to itself, with the firewall as the secondary.

Completed steps, and have the same result.

ETA: The url link appears different then it should be

https://<servername>/exchange/eurl.axd/69a1e852fbb85e4d84a6f65fcdcb2c56

Ah -Uhm. Well - I don't know what has changed other then I have plugged at this, and now it is working. I was going to say that it's working right in FF, but IE it wasn't,.. but then I re-typed the url and it's working.

Last thing done:

cscript iisext.vbs /EnFile C:\WINDOWS\Microsoft.NET\Framework64\v4.0.30319\aspnet_isapi.dll

Sometimes services need to be restarted so it could have been a change before that you made, for example, recreating the virtual directories, etc

Everything is still running normally this morning so I am going to say that it is resolved.

Thank you.
