We have 2 instances of ArcGIS server 9.3. One serverA we have successfully published a map service.
Now I took the same mxd file and tried to publish on ServerB. But I get a lot of warnings saying The Layer "xxx" is invalid. Also the following error:
Method failed.HRESULT = 0x80004005 : Unspecified error .

Please help, what could be the issue?
