I have a somewhat unusual situation in that I have a LAN that is NOT connected to the Internet that I need to keep patched. Unfortunately, the documentation on how to do this sort of think is scant at best and so far I have only been able to make it work partially. Let me describe my problem in detail and I hope someone can help.

I installed WSUS server on a server that is connected to the internet and after selecting the desired updates and patches, they were successfully downloaded. I then installed WSUS server on a server that is on a LAN that is NOT connected to the Internet. I then copied the files from the WSUScontent directory on the server that is connected to the Internet to the server that is not connected to the Internet. I then ran the wsusutil export command to export the metadata files and copied them to the server that is not connected to the Internet and imported them there. The WSUS server that is not connected to the Internet is set to synchronize with itself.

This is where I begin to have problems. When I run a synchronization under Download Status I see the number of files that need to be downloaded in Updates needing files. Below that it shows me the number of megabytes that are required for those files and how many megabytes have been downloaded. The download begins but never completes.

My computers are reporting back to the WSUS server and some patches are being installed, but many of them are not. When I investigate, I can see where many of them have been downloaded - in other words, they are in the WSUS server and available for install, but the computers don't seem to be getting them. In other cases, I it tells me that the files for a particular update have not been downloaded yet. 

This is beginning to be extremely frustrating for me. I have tried to search for updates on the hard disk of my server but I don't see any way to correlate the Update name with the cryptic codes used to identify them. The update ID's don't seem to map to the files names in the WSUScontent directory either. I have checked and double checked to make sure that my settings on both servers, the one connected to the Internet and the one that is not, are the same. 

I have tried just about all the fixes I have been able to find on the Internet with no luck. Of course not many of these deal with my particular situation either. Just to sum up - my biggest problesm are that my clients don't seem to be picking up all needed patches even though they show up as available in the WSUS server and that not all needed files are being downloaded, even though I have copied them from my WSUS server that is connected to the Internet. 

I would greatly appreciate any ideas anyone may have.
