Can't find any information, so I don't know what's going on, but every time I use dcpromo to promote or demote a server, either 2000 or 2003, all the scheduled tasks become disabled. I can open them (after receiving an error that states it can't find the account information) but the 'run as' field is greyed and the 'set password' button is disabled.
The only way I can re-enable the task is to delete it and re enter it. Then it works fine. I have a server that I plan on promoting to a DC soon that has over 20 important tasks, and the thought of having to re-enter those is daunting.
Can anybody give me more information on this or tell me a way to prevent it?
