I have an existing network with one Windows2003 Server for SBS hosting Exchange. Last week I installed another server to host Blackberry Enterprise Server and used a second copy of W2K3 for SBS as it's operating system. After some initial problems with Blackberry, one of their techs said I should make the BES a domain Controller. I promoted the BES to a DC and started to get messages saying only one SBS could exist on the network.
Today I demoted the BES to a member server and now in the system error log I get a message saying "This computer must be a domain controller". and continues on saying that it will shut down in the future.
Are there any workarounds for this or do I now have a useless copy of SBS and will have to purchase a copy of W2k3 standard as well as a copy of SQL?
I know there is a "Transistion Pack" but the theives at Microslut want $3000 for it. Am I screwed?
