xp slow over wan 1

[masteeler]

We have a NT 4.0 domain and a wide area network via dedicated cable modems and adi (software) boxes. XP systems in the building work fine with no speed issues. XP systems outside the building going through our wan are extremely slow booting up and most importantly running any kind of software involving the network. Windows 98SE systems that are older at the same location are much faster??????

Thanks for any help!!!!

How are you mapping your drives from the outside the office PCs?

What is your bandwith?

The pcs are set up to log onto our domain through tcp/ip, wins, and gateway setup. I don't know the exact bandwidth - not the greatest, I'm sure, but there is such a big difference between the xp and 98se pcs....hope I'm explaning this ok...

1. Remove the search for Scheduled Tasks by clients:

By default the "Scheduled Tasks" installed as default in Windows 2000/XP scans shared files for Scheduled Tasks. And it turns out that you can experience a delay as long as 30 seconds when you try to view shared files across a network because Windows 2000/XP is using the extra time to search the remote computer for any Scheduled Tasks.

Removing that functionality will not cause Scheduled Tasks to break, & it will speed up your browsing significantly!

Open up the Registry and go to :

HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/CurrentVersion/Explorer/RemoteComputer/NameSpace

Under that branch, select the key :

{D6277990-4C6A-11CF-8D87-00AA0060F5BF}

and delete it.

2. Patch the Redirector

You might like this then.

Unless the users are heavy users of Active Desktop, and require constant refreshes of their wallpaper from a web site:

Control Panel, Administrative Tools, Services, stop the Web Client service, and set to disable in Startup options.

It usually makes a big difference over WAN links.

This can be pushed through Group Policy.

Great - and just for your info - the latest hotfix from article 811169 - "update to increase the performance of the network redirector" will be ready at 1:30 today (eastern stand. time)...jen

We are getting more and more SP2 releases. MS at the beginning of the month said they were going to adhere to a month-end scheduled update service, and I am guessing this is what you are referring too.


The redirector patch has been available if you are brave and Google hard enough.

masteeler,

For the very brave, are you aware of essentially the Black Viper site for Networking?

In case the Black Viper reference is obscure:

The Network equivalent:

I run pretty much plain vanilla stuff for my networks, but I read and appreciate the advice given in the two sites above.
