Windows 7: Juniper Network Connect 6 for VPN access

Juniper Network Connect 6 for VPN access

Has anyone got Juniper Networks Network Connect working?

I was able to install Juniper Network Connect, but the Juniper "host checker" refuses connection, because OS is wrong: check_os returns false.

Any idea how to work around?

I checked the FAQ from Juniper, but they are saying "we will support when Windows 7 is GA"....

The first time I ran Network Connect on Windows 7, it worked! I was on it for 4 hours no problems.

Disconnected, took a shower, came back and nothing!
It connects, and then disconnects maybe 20 seconds later, and loops doing that.

I have no idea how to fix it. It DID work, so I know it's entirely possible

Windows 7

UPDATE, IT Doesn't work any longer....

I have got it to work, and I can now log in and out of VPN.

I'm connecting to VPN through a web-page that starts the juniper host checker. If Juniper host checker isn't installed, it will install it.

As I hadn't connected with Windows 7 before, Juniper Host Checker was installed, but failed miserably without presenting me with a decent error-message. First I believed it was my beloved installation of virus protection that caused the error, and went about uninstalling it -> bad call...... It took ages. Anyways, I got a new viral installation that I knew would work, uninstalled the Juniper Host Checker and Setup, and tried connecting again with the same results as before.

Then I found the solution that worked once!!
1. Uninstalled the Juniper Host Checker and setup again.
2. Ran Internet Explorer as administrator and visited the VPN connection page.
3. Juniper Host Checker was installed (perhaps with admin rights, if not I was lucky...)
4. Connection successful

Have Tried signing in and out a couple of times and it works like a charm :)
Update: But now it doesn't

My company uses Juniper SSL VPN also. I am using Windows 7 build 7068. The Host Checker works but it does not allow the Network Connect to show on the FireFox or the IE 8 page. The reason is that it says that I need to run Windows Update. My Windows 7 installation is up to date with updates. I guess it is just confused about the OS. Anyone have a work around for this?

Here is the work around...

So when you first boot up, use the F8 key to get to the advanced boot menu.

Select the " disabled digital signature drivers".
Let the computer boot as normal.

Once at the Desktop screen, use the start button.
Navigate toward the IE, and do a RIGHT click on it.
In the drop down menu, select the RUN IE in administrator.

Once IE opens, use your VPN address, so Juniper will download and install the drivers and software.

The Connection wizard opens and establishes connection.

My boss and I use this method to work while away from the office.
This works everytime.

Good Luck
