Hey folks, I've been having issue with my Exchange System Manager, and the great guys over at MSExchange.org were able to help me out a lot, but one of the Mods there came to a conclusion regarding my issue that he, and certainly not I quite know how to resolve.
I read your post on MSExchange.org concerning the issue you are having with your SBS server. Iím not in anyway an SBS expert but based from the issues you are having and with ISA also running on the same server; it sounds like a Windows Service Pack 2 RSS issue! What SP are you running?
Can I remove the ISA Server on Server#1 and set it up on another SBS Server?
Should not have to; just do as directed in the KB and you should be golden! One thing that I have ran into with this is that you may need to update the NIC drivers as well after running the patch and disabling RSS and TCP offloading to get everything working properly.
Reading through your MSExchange.org thread you made reference to your NIC configurations and binding order. From what I could tell you have miss configured the NICís. First, with the Network side NIC being disabled, ISA would be considered running in ďhork modeĒ. (single NIC) Running with only one NIC configured, the ISA firewall service is going to cease to function. You need to enable that internal NIC. As I previously mentioned, you may need to update the NIC drivers. I would uninstall the NIC drivers and then reinstall them and restart the server after doing so. Then run through the NIC configurations and set them up properly. Please reference the article below for configuring your NICís.
Okay Rotorblade, will do when I get in tomorrow, I applied the patch remotely. I suppose I've somehow managed to get OWA/Exchange to perform with the configuration using only 1 NIC for sometime by fluke.
UPDATE: I came in after applying the patch last night, and attempted to execute the workarounds. None of them applied to me though (no updated NIC drivers, Receive Side Scaling Value was already at 0 as was the Offloading Support).
Okay, moved on to the tutorial... and the configuration was absolutely fine, still have internet and websites, but no change in the ESM. The Server still cannot "find the RPC Server" and I still cannot attach the correct IP address to the STMP Virtual Server.

If negative results again then will need to get more specifics on your ISA setup. If you could provide (not jeopardizing your security of course ) information on the ISA system policy and firewall access rules, NIC IP specifics etcÖ. Anything you can provide will help. ISA could be blocking? The ESM relies on Netbios/Winns so Iím thinking down that troubleshooting path. Is your DNSís zone records correct? Maybe you are using a HOSTS and LMHosts file that needs to be updated with the correct IP? Netbios enabled? Can you ping your server by its host name?
Is this server accessible from an internal network? From your description it sounds like your just using it for hosting purposes. Internally, the ESM can run from another machine. Other than moving the mail box in AD using the Mailbox move wizard, you would need to use a utility like EXmerge to export and import or do an Exchange store recovery to the new server. It would be a lot of work but that may be your only option. I would not give up the ship just yet! You need to investigate the problem further to determine what gives.
