MobileMe login failure - OSX Server 10.5.8

10.5.8 Server
1.8 Ghz G5 tower
2.5g of ram

problem: can not log in via the mobileme control panel - or the mobileme website

I tried the mobile me control panel with 2 diff valid accounts and after a min or so I get an account validation error message

Have also tried MobileMe login with nonsense login and receive the same result

Have tried resetting SyncServices and have reinstalled 10.5.8 update

what's more curious is that I couldn't get through to the following apple websites
each time i get a "Safari can't open the page because the server where this page is located isn't responding
and when I tried to use mobile me support via chat it gave me the same message as the above sites

tried Firefox  - same result - can't hit those pages

nslookup does return IP addresses for those domains and subdomains

entering the IP address for those subdomains in a browser yields the same result as the DN

I am trying to avoid installing the server from scratch as it took a long time to get this setup stable

only other apps that run regularly on this setup are Backup (which is disabled now because of Mobile Me) and Carbon Copy Cloner which clones the startup drive to a Mirror drive

A bug (or trojan?) in the OS is apparently blocking the server from accessing those sites. I can't even open an iChat session from this box to troubleshoot with MobileMe support.

I've also tried deleting all the pertinent Preference files.

The sites are accessible from other Macs on the same subnet, so this can't be a firewall issue.

My next suggestion is to get an external drive, boot and install your server os on it. Does mobileme work?

If so, you might have some corruption in your os and you may have to reinstall.

I will take a stab and say you may have the DNS changer virus. Take a look at this link, run the removal tool and test.

Regret to inform you DNS Changer fix did not solve the issue.

What are the DNS servers you have listed on in your network system preferences? Can you try replacing them with and

We did try changing DNS, with no effect.

An OS reinstall is probably the only way out of this one. We may not do it, though, because the server rebuild may not be worth it to the client. We may seek some other avenue for off-site backup.
