Cisco VPN with Windows Vista and Outlook 2007 - transmission hangs when sending email with attachments.
I am using Windows Vista Business with Outlook 2007 and a Cisco VPN client to access my corporate Exchange Server. Everything worked fine until I went on travel last week and connected to a hotel network (both cable / wifi). Upon my return, I could no longer send email with attachments. I can connect via VPN. Send / Receive email. Ping endpoints. Access Sharepoint, etc. Only when I try to send an email with a large file attachment, 100KB +, does the transmission hang.
When I use my Verizon Broadband card , which establishes a PPP connection, the email works just fine over the VPN. I also installed a PCMCIA ethernet adapter and had the same problem, so it is not my internal NIC.
I am using a Comcast Business class ISP connection so bandwidth is not an issue. It appears to be a problem with Ethernet in general.

Tried TCP and that doesn't work and I'm using the proper Cisco client. The strange thing is I can download email with large attachments over the VPN, I just can't send them.
Did you try a reinstall? and I agree, very strange behavior.. and funny that it works using your Broadband card.. I take it that this behavior is also only noticable when your VPN is connected?

I did try a reinstall of the VPN, however Cisco doesn't use an Install Shield utility, so I wonder if traces of the VPN config were left in the registry that could be the cause of the problem.

If this does not work, you might try reinstalling the Cisco VPN Client.. make sure you get the one that is meant for Vista..
