Question - Can I force a machine to use a specific DC for Authentication

October 8, 2008

G'day all

my proxy/internet server (2003 service pack 2) runs a product called

Clearswift Mimesweeper that uses NT authentication to validate user data for

instigation of rulesets and reporting. We seemm to have a problem with some

users the proxy server is using a different DC to the users PC to

authenticate and this is then stopping the users from surfing the web when

authentication fails. The prtoblem appears to be that the proxy server is

using a remote (WAN) DC to Authenticate.

Does anyone know how I can force the proxy to authenticate to a particular

or is there some software that will work?

Thanks

Re: Question - Can I force a machine to use a specific DC for Authentication

Hello Clubsprint,

Normally it doesn't matter which DC's is used, when your replication between

the DC's is running correctly. Please describe your network setup, how many

sites, how are they connected, how many DC per site and how you setup your

DNS.

Did you check replication between the DC's with replmon GUI or repadmin /showrepl

from command line?

Did you configure AD sites and services with the subnets and move the DC

to the belonging sites?

Re: Question - Can I force a machine to use a specific DC for Authentication

Can you not deploy another MIMEsweeper for Web in the other location where the users are having issues ? It's a bit heavy handed, but if your replication isn't working properly then it's a solution.

You could log a support call with your Clearswift partner network who I am sure would be happy to discuss options with you

Re: Question - Can I force a machine to use a specific DC for Authentication

We have a central site with 2 DC's and six regional sites all with a DC.

HODC1 is Schema owner, Domain role owner, PDC role ,RID pool manager and GC

server

HODC2 is Infrastructure owner

I've checked the replication and all is OK

AD sites and services setup is fine and all replication is working (our AD

site is about 7 years old)

Links for regional sites are between 20Mb and 2Mb per site.

The problem will generally effect users after they change their passwords

but will sometimes just appear out of the blue.

Clearswift verdor and local office have said it's a problem when the

authentication of the user and the proxy server happens at different boxes,

hence I want to force the proxy to authenticate to HODC1.

Thanks

Re: Question - Can I force a machine to use a specific DC for Authentication

Hello Clubsprint,

If they are in one site passwords are updated immediately between the DC's,

if they in different sites the lowest replication time is 15 minutes configurable

in ADSS. So depending on which site the password will be changed the new

password needs time for replication. So even to set the proxy to one fixed

DC will not help if the user is in a different site then that DC.

Here's my problem. You check replication and there are no errors however

we will get a replication problem for a number of days. It's the weirdest

thing.

It's annoying enough mangement that there a noises about removing the

product altogether.

Re: Question - Can I force a machine to use a specific DC for Authentication

Hello Clubsprint,

Plese post an unedited dcdiag /v, netdiag /v and repadmin /show repl from

all DC's here. If the output is to big pipe to a textfile like this:

dcdiag /v >C:\dcdiag.log

Re: Question - Can I force a machine to use a specific DC for Authentication

Hello Clubsprint,

I think you will use private ip ranges like 10..x.x.x 192..x.x.x or 172.x.x.x

so with this ip's nobody can reach you. Your server/domain name you can replace

like server1 or domain.local.
