This is quite a common problem on various platforms and machines.

Dell
There have been problems with the GX110 which was due to the video drivers. Loading the latest version resolves this.  There seem to be numerous problems with the GX1 which are still being investigated.

IBM
PROBLEM: There are two versions of IBM's software. Client Access Full and Client Access Express. When Client Access Express is installed on an NT4 workstation (with SP4, 5, or 6a) an intermittent problem occurs in that you cannot log into the domain on main login. Also, when working, the domain will "disappear" and you will lose access permission's in the domain, as well as possibly losing the permission to shut down the machine - Admin or not. It also causes the system to appear to be "hanging" but it's just that it slows to a crawl. Removing the IBM Client or the SMS client resolved the problem. A registry edit workaround was made on the MS Public newsgroups which makes the Client Access software depend on a service (protected storage service) so that it doesn't "collide" with the SMS Client. It was mentioned on the newsgroup that a hotfix would be available soon from Microsoft but it seems like the issue has been dropped.

RESOLUTION: To resolve this problem:

1. Start Registry Editor (Regedt32.exe) and select the following key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Cwbnetnt

2. From the Edit menu, click Add Value, and add the following value:

Value Name: DependOnService
Value Type: REG_MULTI_SZ
Data: ProtectedStorage

Note: Some versions of IBM Client Access software do not install the following services.

3. Add the same value to the following keys as well:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Cwbrdr
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Cwbrxd

General
It seems that upgrading DCOM to at least version 1.2 and WMI to version 1.5 on Windows 95 clients helps with these. You can easily see if you need a hotfix from Microsoft by:

1. Install DCOM 1.2 and reboot.

2. Install WMI 1.5 and reboot.

3. Repair Remote Control.

You'll know within 30/60 minutes if you need the hotfix detailed in 266232 "Windows 95 Clients Hang When Remote Control Agent Is Installed". This hotfix cures the out of resources error caused by the Remote Control installation locking up.

You may also need to look at 269411 "Windows 95 Clients May Hang After Upgrade to Service Pack 2".
