I forgot some details about your problem. Is it 2000 or 2003 domain? How many domains are you running? Mix mode or native, I am talking about windows? How many DC's and how many GC's? Do you have NT 4 domain somewhere there?

PDC and ADC these two are Global catalog servers in the forest and I able to replicate to both GCs from child domain and from child domain to GCs. And I can able to create users with exchange mailbox in other child domains( except one child domain in which I am facing problem while creating mailbox for a user) installed in the same forest. What could be the causes for this error. Once again thanx robin ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp ------------------------------------------------------ Visit TechGenix.com for more information about our other sites: http://www.techgenix.com ------------------------------------------------------ You are currently subscribed to this MSExchange.org Discussion List as: aalmassud@xxxxxxxxxxxxxxxx To unsubscribe visit http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Report abuse to info@xxxxxxxxxxxxxx
