Did you follow the link James provided? I think that doc should answer
all 3 qs. Sincerely, D�j� Ak�m�l�f�, MCSE+M MCSA+M MCP+I Microsoft MVP - Dir. Services / Security www.readymaids.com - we know IT www.akomolafe.com Do you now realize that Today is the Tomorrow you were worried about
Yesterday?� -anon -----Original Message----- Thanks James. You've responded to scenario 2 only (I believe) - can you offer any
comment on the other 2 scenarios? A simply yes/no will suffice :) If no, can you point me to an article
that explains the correct behaviour?

folder. Inside that are the site names and an _tcp folder.� This contains the
SRV records that are registered for that site.� Once a client is site aware
(after first logon) my understanding is this. 1) The client queries DNS for a list of DCs in its site.� It will then
try them in a random order.� If nothing is returned, or this fails... 2) The client will query DNS for a list of DCs in the domain.� It will
then try them in a random order with (I believe) 100ms time out for each
before contacting the next. Gil Kirkpatrick wrote a very good article on controlling this topology
with SRV record priorities (ie.lower records are provided first and when
they time out remaining records are provided), and on setting manual site
coverage. http://www.windowsitpro.com/Windows/Article/ArticleID/37935/37935.html We have used this somewhat, setting the SRV record value for all DCs to
16, except for our hubsite (left at the default value of 0) for the
domain.� In our scenario the client will 1) Check the site, if there is nothing. 2) Check the hubsite, if they both time out 3) Check every other DC in the domain. Hope this helps; James R.
