Hi. We have a Windows NT network with 2 MAC G4's. All users log into the NT server and access their individual MAC volumes. After a user has been on for about 3 hours, their MAC freezes up and has to be rebooted and an ERROR event ID 12053 appears in Event Viewer saying that their session was timed out and they were disconnected from the server. It is our server disconnecting them and not the client trying to shutdown or close. We have 52 MAC volumes on a 40 GB drive taking up 25 GB hard drive space and consisting of 59,000 files and 4500 subfolders under those 52 MAC volumes. Is this a problem with the non-paged memory pool? I see that it max's out in the performance monitor quite often. The server is a DELL with 256 MB RAM and dual processors.The MAC's actually have more RAM than the server does - one with 512 and one with 1 Gig. How can I solve this problem? Do I need to add more RAM or remove some of the MAC volumes that are not in use right now?

What version of Nt are you running. We have 350 Mac users and no problems. Running NT4 service pack 6. Why do you have so many Mac volumes? We have one mac volume per drive and each user has a folder setup. This supports both the NT and Mac users on the same volumes. We also get ID 12053 but only if they stay connected with no activity for an extended period of time. Are the Macs sleeping when this happens?

We have NT 4 SP6 installed. As to why I have so many MAC volumes - I thought that I had to do it that way so each user had their own folder that only they could access. We have many clients using our free job search centre and they need a place to store their graphics files which are sometimes quite large. I believe I tried the one MAC volume thing before with clients each having a folder under it but they were able to access each other folders which I can't allow. As for the timing out - the user gets the machine for a 3 hour time slot and they are working on the computer when the time out occurs - usually near the end of their 3 hour session. They have a file open at the time and are forced to restart their computer and end up losing their work. I am thinking that in the past when I had the one volume that maybe I did not assign the appropriate permissions to stop clients from accessing each others files. I will try it again and see it makes a difference. Thanks.
