This has been doing my head in for five days. I thought it was an issue with my system but looks like others have exactly the same problem.
I have a W2k3 R2 x64 SP2 running manager, four W2k3 R2 x64 SP2 clients (including the manager server) and one W2k 32 bit client. None are connected to internet.
I update my definitions weekely on Thursday mornings and my last update of 64 bit definitions was on the 4th with definitions dated 3-3-10.
I no longer even have any 64 bit definitions on my server because so far over the last few days I've tried:
1) Clearing out old definitions - No effect. A folder for 100303050 even reappeared in the {1CD85.... folder!
2) Upgrade manager from 4r1 to RU5 - No effect
3) Uninstall manager, re-install RU5 manager and reconnect all clients - No effect. I don't even have a {C60D.... folder any more!
My manager processes the jdb file but only updates the manager with 32 bit defs. Could the jdb only contain 32 bit defs? The definitions download site appears to have defs for 32 bit or 64 bit server but they both point at the same jdb location so I don't think there is a specific jdb for 64 bit or 32 bit server.
