Windows Serv edr 2008 problem

When I turn off compression in my winsock transport, I get an error
which says nexusdb: customdescsdescriptor class is not supported

The error occurs in the following routine:

procedure TnxBaseTableDescriptor.LoadFromReader(aReader: TnxReader);


if ReadBoolean then begin
s := ReadString;
CustomDescsDescriptorClass := TnxCustomDescsDescriptorClass(
TnxCustomDescsDescriptor.FindDescriptorClass(s));
if not Assigned(CustomDescsDescriptorClass) then
-------> raise
EnxBaseTableDescriptorException.nxCreate(DBIERR_NX _UNSUPDICTDESCR,
@rsClassNotSupported, [csCustomDescsDescriptor, s]);
if CustomDescsDescriptorClass <>
tdCustomDescsDescriptor.ClassType then
raise


What additional information do you need to help identify what is causing
this problem.....

thanks ....

If I set the winsock compression to 1, the error disappears....

another test ... compresion 10 RLE fails ...with the same error as no
compression, but any zip compression level 1..9 works ....

Is this with the standard server? How do you connect?
