Connection fails if server and clients are in different subnets

[teggers]

Hello,

our Volume License Manager (v2.1) is running in another subnets than the clients (All machines are running under Windows XP-SP2 without Domains or ADS, just workgroups).
The server is in subnet A (192.168.42.0/24), all clients are located in another subnet  B (192.168.50.0/24).
Routing is properly configured and is working fine, traffic to the specific hosts is not blocked by a firewall. We can ping every machine,
open telnet connections to the NILM, everything works.

But if the clients try to connect to the remote NILM (both local client NI License Manager and VLM port settings are correct)  their connection attempt always
times out with error code "NILM10"
(I already read the mentioned KBs, no solution has helped so far). This is true if clients and server are separated.

For testing purposes, i plugged one client into the server's subnet (server's IP: 192.168.50.250, client 192.168.50.10)
and it worked perfectly. Is there a reason why  server and client have to be on the same subnet or is it some other kind of problem that I am not aware of?

Thank you.

Thorsten

Hello Thorsten,

Did you add the server's domain to the client computer's DNS settings. To do this, complete the following steps on the client computer:

1. Open Local Area Network Settings from the Control Panel (Start»Control Panel»Network Connections»Local Area Connection)
2. Click the Properties button
3. Select Internet Protocol (TCP/IP) from the list of network components
4. Click the Properties button
5. Click the Advanced button
6. Change to the DNS tab
7. Ensure Append these DNS suffixes is selected
8. Click the Add button
9. Enter the domain suffix of the license server and click Add
10. Close any open dialog boxes, choosing OK and Close as necessary.
