Cannot connect to MSDE on a W2003 server

I have installed MSDE with SP3a with a instance name on a
Windwos Server 2003 Enterprise edition.
The install works fine.
I installed the client software on a W2k en W98 client
PC, the install work fine.
When i run the program, the program normaly sees the
servernaam and instance name.
This do'nt work on the Windows 2003 server. (2000 server
works fine)
Have enyone a idee?* Did you apply the SP3 version of MSDE? If not TCP will be disabled on
Windows 2003. You must apply SP3 before TCP connections (the default from a
remote client) will work.
* What error do you get when you try to connect?
* Do you get the same error from Query Analyzer, OSQL, and Enterprise
Manager or just from your application?
* If you force TCP, named pipes, or shared memory does it start working or
change the error?
* Do both remote and local connections fail for each protocol? For MSDE
2000 SP3 remote connections are disabled by default, you have to enable TCP
and/or named pipes on the server side before remote connections will work.
