Why is initial access slow on network?

By jim_kinee ·
I have recently added a Windows 2000 w/SP1 system to an NT4.0 w/SP6A network. When opening a file by double clicking in explorer the file takes an unusually long time to open (30 seconds or more for a 20K file). When opening a similarly sized file through the application the file opens almost immediately (as it should). It does not matter what the application is as the problems exist using MS Office, TIFFs or Adobe Pagemaker files.

The Server and the W2K system are using TCPIP. All other machines on the LAN are NT4 or W95 using TCPIP and do not experience the same problem.

What could be causing the problem?

Everything works fine on the local machine. It is when it accesses "non-executables" on the network.

Hi Jim.
I had this problem once and found out that the real culprit was Virtual Memory and not the network. Try increasing your pagefile size. If you have 8gb Hard Disk, and 128mb RAM, then you can have pagefiles on 2 disks. On the drive where NT is loaded, the minimum should be 138mb (of course this will be less if the NT drive is less than 2gb). The next drive should have ample space to have a pagefile of 1gb. Be careful however. Check your hard disk space before increasing the pagefile size. It may slow down your system if the pagefile is too big in comparision to your disk space. One more thing. Do not scatter your pagefiles all over. Ideally, you should not have more than 2 pagefiles.
All the best! And do let me know if it works.

Paging files is set to 384MB to 778MB. There is 6GB free. And everything is partitioned as one drive.

Optimiser is correct. I have 2k running side by side with my nt4 and win98 machines on a shared network, and I was having slowdowns when accessing files on the various machines NOT 2k. I am using 2kPro, if that makes a diff, and as soon as the page file sizes were sorted out, rather than letting the OS take care of it, the problem essentially evaporated.
Be careful to set your page file sizes according to the available space on your drives, and do try to never go over 15% of the total drive space.
Just my opinion.
let me know how this works out.

I can't remember the details off hand, but I do remember there being an issue when running a mixed Win2k/NT4 environment where a WINS server is necessary for the two to communicate properly....might be worth a look.

WINS is running on the NT4 server. Also pointed to a different server running WINS. Still no luck. Thanks.

It seems your client has to broadcast to find the server with the shared files.
If there is a wins server in the lan try to check client wins configurations otherwise install wins service on a server.
Try to open network neighbors; if it is slow too then try to estabilish who is the master browser in that network.
Disable browsing service on win2k client or set it to "non browser". It has to NOT become browser.
Good Luck

Jim- COULD it be basic DOS. IF all the OS's mentioned are standing on DOS ( not sure abt 2K0 then it may be a problem of allocationto pper and lower Memory. Did 2K depart from the group?
