Error - "An error occurred while reconnecting to drive S"

[Harrison Midkiff]

Hello:

I have an network application that my users user pretty heavily. They
connect to it on a mapped drive "S". Over the last week many of my users
have complained that they are getting kicked out of the application. One
user said they got a message "An error occurred while reconnecting to drive
S:" This is the mapped network drive the application runs on. I am
beginning to think this could be a connection or time out problem between
the clients and the servers.

Does any one have any ideas or suggestions of what I should look at to
address this? The NICs and switches are all 100MB.

I think you really need to focus your attention on the share that this mapped drive points
to, the users permissions and the quality of the data on the shared location.

Thank for your reply....

I just noticed something about the shared folder. I noticed that it is
configured for "Allow caching of files in this shared folder". I am just
starting to look at that setting. Do you think that could cause problems?
I have about 100 users hitting it and the application typically opens 100 or
more files each. I think if I disable this feature it may not address this
issue, but it might help speed it up?

Any ideas?

Hi Harrison,

Thanks for posting here.

The cache option is used to limit the offline folder settings. If no
offline folder is configured on the client side, this option doesn't effect
the performance of your Windows 2000 file server. Anyway, you may disable
it.

To further analyze this issue, I suggest you monitor the performance of
this file server, especially the CPU utilization/Disk read/write and RAM
usage.

If there is always 100 users trying to open 100 files each at the same
time, you need a powerful server with strong CPU(s), large RAM and fast
Hard disks (or disk array). You may also contact the software provider to
see what kind of pressure test they had performed to get a specific system
requirement to fit your environment.

Please check them my using the task manager together with the perfmon tool.

If anything else is unclear, please feel free to post back.

Have a great day!
