global catlog

[Srinivas Acharya]

Hi All,
I have two domain controllers in a single site, single
domain network. One is acting as global catlog server. What
is the difference between active directory data store of
global catlog server and other domain controller?. Are they
of same size?. Do they contain same amount of information?.

Regards,
Srinivas Acharya

The Global Catalog contains a partial replica of the domain Active Directory
for every domain in an enterprise forest. The Global Catalog server
replicates a copy of all objects from every domain in the forest, but only
contains a subset of each object's attributes. The attributes that are
replicated by default are those that are those used in most common queries.
The Global Catalog provides one information store that can be queried to
locate forest-wide information.

In addition to Pauls post, in a single domain environment it is usally best
to make all DCs Global Catalog servers.

And in a single domain environment, the difference in size would be hardly
discernable.
