Status: Verified
SYMPTOM(s):
Msngr: the specified service name does not exist or has a bad format. (5825)
Msngr: Cannot find default service name to serve web request. (5830)
Intermittent problems
Use an IP address instead of the Host name to reference the machines.
Links to WebSpeed application fail
Most of the time happens when there is a firewall between the messenger and the name server
FACT(s) (Environment):
WebSpeed 3.x
All Supported Operating Systems
CAUSE:
WebSpeed 3.X uses the UDP protocol for communication between the Messenger and Name Server. When the messenger sends a request to the name server, the name server responds to the host name instead of to the IP address. When the name server tries to send the answer back, it won't reach the messenger if the name server cannot resolve that name to an IP address. It resolves this name using a variety of ways, hosts file, DNS, domain search order list, WINS, netbios broadcast and so on. If it takes too long to resolve it, the messenger often gives up and sends an error back to the browser. In a firewall environment it is really common that each machine doesn't know the other one by name.
FIX:
Entering the IP addresses and host names in the hosts file on both machines, and using the host name to reference the machine in the configuration files, has resolved several issues of hanging, messenger errors and links not responding.
