An old webservice doesn't start correctly anymore.

Buba

Not sure what has happened, this was running on a test server and did work.
Now both services starts fine, but not able to access the webservice anymore. Checked the RTC and it does work.

Here is the eventlog of the failure.

This is Nav 2009 SP1 btw.
Any suggestions?

Did you ever resolve this issue? I'm experiencing the exact same problem (error message) and trying to solve it.

Can you access the WSDL for the webservice, get the list of companies (i.e. http://servername:7047/DynamicsNAV/ws/companies), etc.?

Also, a long shot, but be sure there are no pending Windows updates. On the rare occasion I have had issues when pending updates are ready but need a reboot or the like.

The problem seems to have been resolved by adding the Dynamics NAV server to Trusted sites.
A reboot was also done at the same time, this could have had some effect as well.
Weird.
