Clients Hanging When Receiving Attachments

[JezEling]

Hi All,

Im not sure if this is the best forum to ask this in but here goes. I have a 2000 Enterprise Edition Exchange Server which has run without any problems for a few years now. However recently my clients, around 140 of them, are complaining that their Microsoft Outlook sessions keep hanging whenever they recieve an email with an attachement. Inital I thought it could be client Anti-Virus so I disabled it for testing but the hanging still occurs. I have now tried all I can think of to try and solve this problem but all to now avail.

Has anyone suffered similar problems, or does anyone have any further suggestions as to how I might troubleshoot this problem some more.

Any help would be much appreciated

are clients XP...if so, try disabling the web client service and see if it helps you at all

What they are saying is true behavior by default...it will hang until the attachment is downloaded fully....so my next question...how big of attachments are we talking...and what kind of format (pdf, doc, txt, etc.)....and is there any differences in behavior based on the file type?

The clients are a mixture of Windows XP (SP1) and thin clients running 2K Server with Citrix.

The attachements can be anywhere between 3KB and 3MB, and it tends to happen with all file types. There does't appear to be any differences in the behaviour, Outlook seems to hang, and will come back to life, however occasionally Outlook with have to be terminated with task manager as it never comes back to life.

Do you have AV software on the Exchange Server?
If so what type?
Are you scanning the m:\?

 

[JezEling]

AV is installed on the Exchange server, i've got Mcafee Groupshield running for internal scanning of Exchange and i've got their VirusScan Enterprise running for file level scanning. I've check the VirusScan and it doesn't seem to be scanning M: drive.

Version numbers please?

 

[JezEling]

Groupshield Version - 5.2

VirusScan Enterprise - 8.0

 

[RRM]

Change the scanning timeout in Groupsheild. Increase to 3000 seconds.

Thanks for the reply, I have changed the setting and I will let you know the outcome.

If that isn't high enough you may need to increase further.
