I would like to update records on two server simutaneously,
error on any update statement would cause another to rollback.

I searched on web and
I would like to use
a) Linked server
and
b) ROLLBACK TRANSACTION in store procedure

1) Is this the best way to do transaction rollback?
2) Is that MSDTC must be enabled and firewall port 135 need to be opened when using Linked server in store procedure?

is it straight update? ie is the table structures in both servers same? if yes, isnt it enough to enable replication between them to pick up the changes automatically? if you want near to realtime sync up use transaction replication.

Thanks for your reply, the table structures in servers are not the same and I just want to share one of the tables, any suggestion? thanks.

Database structure similar to the following illustration:

ServerA
-DatabaseA
--Table1
--Table2
--Table3
--Table5
-DatabaseB
-...etc...

ServerB
-DatabaseA
--Table4
--Table5
-DatabaseB
-...etc

i was not refering to database structure but what i was asking on was on the table structures. if corresponding tables are same in structure you could use replication. other wise you've write a process which will run according to schedule and does this update on backend based on update on corresponding table on main server. But there'll be a obvious delay before which the data changes will get applied

Thanks again.
The only one table I need to synchronize is in the same table structure.
Will replication affect other tables? Thanks.

nope...replication wont affect others. you'll explicitly select the tables that should be included in the publication for replication
