we have 4 exchange servers 3 5.5 and 1 2003 i recently i removed tbe first 5.5 serverfrom the org. now i have 3 sites a,b, and,c. Site a had 1 5.5 and 1 2003, site b has 1 5.5 and site c has 1 5.5 server. i removed the 5.5 server to site a. everything seemed to be ok. but now i look at the gal's on the other sites and user and groups that i deleted from site A still show in B and C. i thought i would give it some time to replicate but it has been about 5 days and still nothing. my app log is full of msadc event id 8139. stating something about making sure the time is correctly set, which is impossible due to the fact that site b and c are in the uk and site a is in the states. does anyone have any ideas how i can fix this problem? thanks scott
