I have a SQL 2005 server hosting a DB in DOMAINXYZ. I am trying to acces the DB remotely through a VPN connection using the vendor provided client. Once connected to DOMAINXYZ throught the VPN, I can ping the SQL server by DNS Name and IP address. When I try to connec to the DB using the vendor provided front end client I am presented with an error message that states "Could not establish a connection to the database server."
I have checked the ISA logs and the traffic from my PC is being allowed into the network. Check the log file on the SQL server reveals errors in the Application Event Log; Event ID 17806 - SSPI handshake failed with error code 0x8009030c while establishing a connection with integrated security; the connection has been closed.
PCs on the same domain as the SQL server using the same client have no issues connecting. This particular client is on a different domain.
