I'm getting this error whenever I hit the "ArcMap" link on the top of the service rest page:

Unable to create layer file for map service 'Fundamentaldata/BaseMap'

Code: 500

The other links (Explorer, JavaScript, Google Earth) are working fine.

Any idea??????

ArcGIS Server Java 9.3.1 +SP1
Windows 2008 server

Thanks in advance.
