The culprit are not apple applications on Windows Vista SP1
===============================================
Hi,

When I used to connect from home to my company network through my personal laptop running Vista SP1, the connection used to drop every now and then. I called our company IT Service desk and they gave steps like
1. Connect to different switch - VPN url (our company runs multiple switches spread across geographies).
2. Uninstall bonjour service which comes with Apple applications (I was not running this service as I do not run any Apple application),
3. Uninstall Java installed on my laptop
4. Clear browser cache, etc.
However none of it fixed the problem. I was about to bring my laptop to office to hand it over to IT service desk for them to fix it, when I tried to do some googling. I found the post below at: http://www.enusbaum.com/blog/2008/04/18/does-your-juniper-vpn-client-keep-disconnecting-after-you-connect/ relevant to my problem and a possible solution.
===============================
1. Hi,
This is indeed an issue on Vista SP1 Wireless, and sometimes Wired connections too regardless of Bonjour being installed.
If you want a fix, you need to go into the TCP/IP properties of the network interface you are using, and choose “Advanced…” Under interface metric, untick “Automatic Metric” and enter “1? in the box.
Seems to be an issue with the Vista TCP/IP stack but doesn’t affect *all* installations.
Cheers,
Con
===============================
I applied the above step to all network adapters on my laptop (LAN connection – wired, wireless and Juniper) and it solved my problem. Hence, thought of sharing it with you, so that other users facing this problem can fix it.

Thanks,
Shashi

I had a similar issue, im off-site using an ADSL link in from another office but every time I connected to my main site I would lose connection after approx 20 seconds losing all my IP settings and have the DHCP client hanging trying to establish a new connection, I would then have to delete the Juniper applications to re-establish a connection to the ADSL router. I tried all of the above advice but did not have any of the mentioned services running. I have found a work-around for this which I hope may help folk in the same situation, a fairly easy one in the end. I assinged myself a static address off of the range issued by the router and havent been disconnected since. It seems the client had an issue with my DHCP service?!

Mate, thanks a bunch! I recently installed itunes just to manage my ipod through my company's laptop and this started giving me trouble. Your post quickly got me into action, without pulling much of my hair(I have only little left)

That same behavior will also be seen if the Juniper VPN Network adapter gets disabled. It should always be sitting in the "cable disconnected" state when it's not in use. If it gets disabled it'll still show connected for a second and then disconnect.
