hello . how are you all
I am alex. new member and happy to be here.
I am a net admin of about 180 computers. because of management changes in the corp , some of "fool brain "managers decide for us to be CHILD of another domain .

now ,I have 2 DC ( main and additional ) in my net. and 1 ANT.VIR srv and 2 FS srv. because of our corp is joined to the new big corp , we should use their applications that run from their APP server. those applications are all "ACTIVE DIRECTORY AUTHENTICATION" based.so they forced me to be child of them JUST for "AD authentication"
I have two ways :
1- obey them and demote my domain controller to child domain.
2- implementing a trust relation ship between my dc and theirs.

if I select the first , I think that this is so "time consuming " for 180 computers and 220 user profiles( there are some computers with multiple user profile)
because of:
A- migrating user profiles ( there are all local, NOT roaming )
B-MY DOCUMENTS folder ( I cant use "my document redirection" because "mydocument" folder is exist in drive D but with deferent names for some users)

I hardly select the second solution , because my manager FORCED me to become child of them. and I hardly refuse.:

is it true to select the first solution or i should select "trust" ? what i your idea?

dear "site admin" :
I searched in topics, but I did not find a problem similar to mine.

thanks all.
alex.

You don't create trusts between DC's [unless in same forest] but between forests in 2003 AD. You have "ad authenication" now so that unto itself is not the reason to go to a child domain.

A forest trust would be easier but would also be a limiting factor for future consolidation.

Doing away with your forest and making your servers DC's in their forest, especially if there is a corp app server they want everyone to use, makes good sense.

I'm sure this is not what you wanted to hear from the tone of your post. Consider though that with this merger you should now have additional resources to draw upon. You can't and don't have to do this by yourself. It would be a great time to standardize your server and workstation configurations which appears to be a drawback in the planned implementation.
