I have 2 servers.. 1 with W2K SP4 and Exchange2K located at Head Office and 1 with W2K SP4 and Exchange 2K located at a Hosting company.
The colocated server contains about 150 mailboxes for our remote sites and the head office server contains about 20 mailboxes just for head office. The colocated server also acts as a front end for the head office server for outlook web access.
There are netscreen firewalls between the boxes on 2MB sDSL link.
All was working fine until a couple of months ago when within a couple of weeks of each other the boxes needed rebooting or crashed.
Since then I have found that progressively we have got to the stage that replication of the Active directory is not taking place.
If I create users on the colocated server then they do not appear in the Global Address Book for Outlook users.
If I create the user account on the head office server, it does not appear at all in the active directory users and computers on the colocated server.
My question is what steps can I take to ensure that replication takes place?
What are the processes involved?
Is this linked to our loss of OWA at the head office site?
Please help as this has got to the stage where I am thinking of reloading my server..which may or may not work.. andwhich I am loath to do because of the risks involved (reloading beskope apps etc)
