SYMPTOM(s):
Error (5482) running WebSpeed
Unknown hostname <hostname>. (5482)
Unable to connect to NameServer at Host <Host> Port <Port>. (8235)
SMB ports 137-139 are closed when the above errors occur
If SMB ports 137-139 are open, the errors going away
FACT(s) (Environment):
Windows NT 32 Intel/Windows 2000
WebSpeed 3.1D
WebSpeed messenger/web server on 1 machine host1, name server and transaction server on another machine host2, firewall in between
2 machines can ping each other by hostname and ip address
Can not telnet from Webserver machine to transaction server machine if ports 137-139 are closed
host2 is not listed in /etc/hosts file on host1
CAUSE:
Hostname resolution issue. host2 is the name given by Windows networking, not a TCP/IP host name.
If host2 is not in the hosts file on host1, or registered at the DNS, Windows tries to resolve the name using Netbios services, which fails if 137-139 is not open.
FIX:
Add host2 in /etc/hosts file on host1 machine
