Unknown Loss of Browsing/E-mail Connectivity...

[SuperFlyBoy]

Hi,

I have a Toshiba M750 TabletPC running Win7 Pro 64-bit.

Never had a problem until a few days ago, possibly until I installed SpiderOak's latest version, 9810. (SpiderOak is a backup/sharing software similar to Dropbox)

I'm using IPv4 with the following settings:

Fixed IP of 192.168.200.192
Subnet: 255.255.255.0
Gateway: 192.168.200.100

DNS1: 192.168.200.144 (our SBS2003 server's IP)
DNS2: 208.67.220.220 (OpenDNS)

After I have used the computer for a day or two, IE and FF stop being able to browse, period.

This is both on a home network, as well as when using Wi-Fi networks out of the house. Haven't used the laptop in the office so far.

I have tracerouted site names (not IP addresses, thus DNS resolves), which I am able to do successfully.

SpiderOak is not running, but possibly any modifications to the OS/networking might have changed things. However, this could also not be a result of SpiderOak, but rather Windows Updates as well...

Other computers on the network (home) are able to browse the internet.

I am only able to browse the net and get e-mail (Outlook) when I log into a VPN connection, and then it works fine.

I have tried putting in DNS1 as the gateway IP, like all the other machines have, but the laptop cannot browse or get e-mail access - no idea why.

I have tried disabling the LAN connection in Win7 and then restarting it, but this has no effect.

No recent updates of LAN connection/drivers have been installed either.

Any feedback is appreciated.

Amazingly - the problem went away after 30-40 minutes - don't know why! Is there a problem with Win7 that I don't know about??

Hi there!

Is this a work machine? Do you get Group Policy updates to it?

Also, check your proxy settings in IE. Unless you have one configured for work, this should be set to automatically detect settings.

Hi Heather,

Thanks for the prompt reply.

Not sure about the Group Policy updates to the machine - we use a SBS2003 server in the office, but I tend to be connected outside the office most of the time and use the laptop independently of Exchange - actually completely independently of Exchange.

I have configured the server, but have limited knowledge of connectivity with Win7 machines. (and possibly XP ones we normally use - this Win7 machine is basically a test)

Note that both my IEs - 64-bit and 32-bit have the automatically detect settings enabled.

Hmm.

If you think SpiderOak *may* be the problem, have you tried rolling back to an earlier restore point to get rid of it and reconfigure your system to its last known good configuration?
