there is a limitation on the number of VLAN's a trunk on the 2950 can carry, if that limit is exceeded, the VTP mode changes to transparent. I am not sure if the limit was 4 or 64, but anyway, try to limit the number of VLANs carried over the trunk by either using pruning (VTP pruning), or by manually allowing only the VLANs you actually need on the trunk (with the 'switchport trunk vlan allowed' command).
also VTP only supports vlans upto 1000 (I think this is the value). If you already have created VLAN's above this value you will not be able to change the vtp mode to server/client (although you should see an error message).
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
