NMDP? Try reviewing the firewall logs. You're looking fro sc-status codes of 20001 and / or 13301 to indicate errors in the protocol stream. Also, review the IP filter logs. You may see some blocking there. Jim Harrison MCP(NT4, W2K), A+, Network+, PCG http://isaserver.org/Jim_Harrison/ http://isatools.org Read the help / books / articles!
