Do I have to configure windows XP in any way in order to improve the

log in speed and policies synchronization on a slow connection?

RE: Log in to a domain on a slow connection

 

On a slow connection, I suggest you to configure a Site .

Put a GC in your local environment.

Slow domain logons are indicative of a few possible things:

 

1. The workstation (or even the domain controller itself) are using the

wrong DNS server IP address in their IP properties. You may have the

internal DNS server listed, or an ISP, or both. AD's requirements of DNS are

absolute. This means you CANNOT use your ISP's or your router's IP address

as a DNS server on ANY machine in a domain.

 

2. The domain is a single label name. Meaning the name is of the form of

"DOMAIN" instead of the required 'domain.com' or 'domain.local,' etc,

format.

 

3. The domain controller is multihomed, meaning it has more than one NIC or

has RRAS installed, which creates multiple interfaces.

 

4. Network settings, such as subnet mask, and other things, are incorrect.

 

There are more, but this is the basics. Usually the wrong DNS server is

specified, usually an ISP's. AD asks DNS, "hey, where's my domain controller

so I can logon?" If the ISP's or the router's IP address in the machine's IP

properties, those servers will respond, "I have no idea," and the

workstation fails authentication and other things go wrong as well.

 

You can't even mix ISP, router and internal DNS. It must only be the

internal DNS listed on all machines.

 

If you need additional assistance, to help us understand your configuration

to provide specifics, please post an unedited "ipconfig /all" from the

workstation having the problem and from the domain controller too.

 

Thank you.

If this is a new AD domain that was implemented recently, the links are just

too slow. Minimum for GPOs to properly apply, including the default Domain

GPO, requires a minimum of 500Kb. The line is now being saturated by

client-domain controller authentication traffic, especially intial logon

traffic when the client's GetDcList, GetGpoList and numerous other functions

are running in the background at logon.

 

Besides the min 500Kb link speed requirements, when there are 10 or more

clients at a remote location, a DC is recommended to be placed out there as

well as create AD Sites to control logon traffic from those clients to their

local DC/GC only. You can get around that fact by upping the speed. Now for

20 users, I would suggest a minimum of 768Kb to eliminate any question about

the 500Kb minimum, but higher if possible.

 

Parse through the following to help understand more about AD design,

including user, DC and GC placement. Keep in mind, if you are using remote

tools and other utilities and features that eat up bandwidth, it will slow

it down further. If you put Exchange in, that complicates matters and

increases speed requirements.
