Subject Re: MSSQL + Cayenne -> connection problem
Date Thu, 29 May 2008 12:48:19 GMT
Mike,

Try this....you need to make sure the TCP port is 1433 and no value 
specified for TCP Dynamic Port for IPAll in the TCP/IP setting. For all 
other IP's, you can set TCP Dynamic Ports to be 0 and leave TCP Port empty.

It can be configured through SQL Server Configuration Manager.

Cheers,
Bill

I am sure some guy on the other side of the Atlantic ocean will have experience with Cayenne
+ SQL Server. You will get responses within a few hours (different time zone ;-)
