Last Error 56049 Cannot log in to the data source. Database communication Error.
This error message can appear logging in to ProjectWise datasource.
If you check ProjectWise services you might see that they are up and running. Trying to restart ProjectWise Integration Server service and ProejctWise Orchestration Framework service it will not start. This means that the account under which the ProjectWise processes are running, may be locked out, or that the password for this account (which by requirements should have a fixed password) has been changed.
Another possible issue is that the communication between the datasbase server and the integration server has stopped.
Unlock the account or change the password back under which ProjectWise services are running.
On the integration server, check the ODBC connection to make sure the system is able to communicate to the database server. If that fails, then on the database server, check to make sure the database services are running.
