Connection through different network card (OpenInsight 32-Bit)

We are running our OI application on Windows Server 2008. All machines on the network are operating at 100mb/s. We are testing an upgrade to a 1 gig network and in doing so have setup a machine through a second network card on the server, with a cat6 cable and through a 1 Gig switch. The machine connects to the network fine but when we try to run OI we get an error message as follows: (Universal Driver 4.6.0.0) Unable to access Linear Hash files, Error=FS231, File=1. I would appreciate any help with this. Thanks, Gordon

Hi Gordon,
The REVPARAM file in the OpenInsight directory will have serverName=something where something is either the name of the server or an IP address.
If it's an IP address then it's probably the IP address for the 100MB network card on the server.
If it's the server name, then the DNS is probably assigning the servername to the IP address of the 100MB network card.
So, what you need to do is change the serverName= setting for the OI accessing the server via the 1GB network card to the IP address of the 1GB card.

Hi Dave
Thanks for your help. That makes sense and you were spot-on as the server= is setup with the IP address of the 100MB card. I cannot however just change the REVPARAM file as that would affect all the other users on the network. Would it be possible to edit the REVPARAM file to accomodate both network cards?

The REVPARAM file can't reference two servers but this procedure might function as a work around. Change the REVPARAM file so the server is referenced by name instead of IP address. Verify the name is accessible and can be resolved by the 100Mb switch. Your application should still function on the 100Mb segment after this change.
On the stations that connect to the 1Gb switch verify they can access the server's shared. Then, edit the \windows\system32\drivers\etc\hosts file on the machine an add an entry for the server.
For example, the server name is server.fabrikam.com and resolves to 192.168.101.10 on the 100Mb lan. On the 1Gb lan the server's IP is 10.0.0.10.
The hosts entry should read:
10.0.0.10 server.fabrikam.com
This will direct the windows client to the new IP address instead of relying on the DNS settings.
