Installation SP1: Service disabled when opening RTC

Hello,

This week we have upgraded our servers with NAV2009SP1. After installing NAV2009SP1 the servers are restarted.
Opening a NAV2009SP1-database on server 1 with a RTC works very well.
When opening a NAV2009SP1-database on server 2 with a RTC the following happens:
- The database is opened and the Role Centre is shown.
- After 20 seconds the following error occures:
The server net.[url=tcp://]tcp://[/url]<servername>:7046/<company>/Service is closed. The cliënt will be closed.
- The NAV service on server 2 is not started anymore.
- The event viewer of server 2 shows 4 errors (see attachment)
- Opening the information of the first event will give the following:

Service:
User: <username which is opening the RTC>

To check if the database on server 2 is ok I have copied a good working database from server 1 to server 2.
The same errors occured when opening the database.

Does someone have a clue what can be wrong?

Thanks in advance.
