The File Replication Service on the computer %1 cannot communicate with the File Replication Service on the computer %2. Verify that the computer %2 is up and running. Verify that the File Replication Service is running on %2 by typing "net start ntfrs" on %2. Verify that the network is functioning between %1 and %2 by typing "ping %1" on %2 and "ping %2" on %1. If the pings succeed then retry the failed operation. If the pings fail then there may be problems with the DNS server. The DNS server is responsible for mapping computer names to IP addresses. The commands "ipconfig" and "nslookup" help diagnose problems with the DNS server. Typing "ipconfig /all" will list the computer’s IP address and the IP address of the computer’s DNS servers. Type "ping DNS server’s IP address" to verify that a DNS server is available. The DNS mapping for %2 or %1 can be verified by typing "nslookup" and then typing"%2" and then "%1" on %1 and %2. Be sure to check out the DNS server on both%1 and %2; a DNS problem on either computer will prevent proper communication. Some network problems between %1 and %2 can be cleared up by flushing the DNSResolver Cache. Type "ipconfig /flushdns". Some network problems between %1and %2 can be cleared up by renewing the IP address. Type "ipconfig /release" followed by "ipconfig /renew". Some network problems between %1 and %2 can be cleared up by resetting the computer’s DNS entry. Type "net stop NetLogon" followed by "net startNetLogon". Some problems between %1 and %2 can be cleared up by restarting the File Replication Service. Type "net stop ntfrs" followed by "net startntfrs". Some problems between %1 and %2 can be cleared up by restarting the computers %1 and %2 after closing running applications, especially dcpromo. Click Start, Shutdown, select Restart, and click on OK. Other network and computer problems are beyond the scope of this event log message.
