We had a fully working BP 5.0 running atop IIS 6.0 since last year when we upgraded from BP 4.0 to 5.0. Our GP is 2010SP3. The certificate was due to expire on Feb 2nd (this week-end) and IT ordered a new one from Entrust with the same FQDN for our BP server (the server is accessed from the outside world, thus the SSL certificate).
They replaced the old SSL cert with the new one by importing the SSL cert into the server. After restarting IIS, they thought everything was fine because they only checked the home page of BP... but not the sub-sites for the TimeSheets, Expenses and requisition management... all those pages fail to load with an error 404 when trying to load the web-parts of BP.
We checked every possible places to see if something else would have changed in the IIS configuration, but no luck. Unfortunately they did not thought about taking a snapshot of our Virtual Machine before changing the certificate... so we can't go back to a previous state.
This becomes an urgent business matter since no user can enter any transactions in the BP for now and we're at month-end.... several expense entries are due for today.
Thanks in advance for any advice and hints.
