Fault -617: "Unable to get distro"

Hi,

Since I moved my ZenWorks server to a new system (still on RedHat 3),
distro and software info are not updated in ZenWorks. Everything else is fine.

From a client:
Jun 9 08:58:11 [14428] Package hash successfully sent
Jun 9 08:58:12 [14428] Handling RPC connection

From the server:

getPackageList, '52734371-877e-4be8-b92e-5cfd692ff712',

-617: "Unable to get distro for 'b1bc4f65def02cf55824b51c7b6944f3'">')

Anyone is aware of a procedure to migrate to a new system?

Thanks,
Martin
