Citrix Metaframe 1.8 50 percent explorer.exe utilization

Dear Sirs,

We are running a Windows NT 4.0 Terminal Server which is patched with SP 6A. On top of this machine Citrix Metaframe 1.8 is installed with SP4 (build 663).

Everytime a user tries to logon, the authentication is almost immediate, however for some reason after the desktop is shown they have to wait for almost 1.5 minutes before their hourglass disappears. The system itself is running on two (old 450 Mhz Xeon processsors). 50 percent of the CPU is being used because explorer.exe steals that processor time for those 1.5 minutes.

I have already tried to repatch the OS with SP6a and the Citrix Metaframe with SP4 but this did not solve the problem. Any pointers or hints what might be causing this?

Looking forward to your replies.

Regards,


Nils

Hi Ahmedbahgat,

It runs with 1 GB of RAM. I cannot add any more because all the memorybanks are full. My feeling is that it is not the memory because this problem occurs even if there are hardly any users on the system.

ok possibly the system registery is exhuasted, I always see this on all windows operating systems, after a few months of use, it seems that refreshing the OS is the solution, youo may try to re-apply latest sp for both NT and citrix

One other place to check is:
Do you have any custom services that access remote shares?
Try to disable such services one-by-one to see which one is a problem.
May be a monitoring application or Fax client.

Another place to check is the printers.
Citrix attempts to automatically map default user printers and if it takes time to properly authenticate them - here's your explorer freezing.

I know it is not pretty, but try to:
1) install all end-user used printer drivers;
2) install printers locally and direct ports via IP;
3) disable automatic Printer mapping and COM mapping (just as a test first);

If this is the problem, then keep it disabled and make a script to set locally installed Citrix printers as each user's default printer so that  they would print via IP and not Via printer automatic mapping.

Authentication takes time when mapping remote drives and if naming resolution is slow and access permissions takes long to varify - users have to wait.
