Windows Forum / Virtual PC / March 2008Can't connect to the Internet!?
Hi, I'm using VPC2007 on an XPSP2 host. I put Vista in as a guest OS. It can see the local network, the host machines and others here, but it cannot connect the Internet. I put a XP guest in and it can see the Net. What's up with the Vista guest? As it is I can't even activate it. Any suggestions? Thanks steve > Hi, > [quoted text clipped - 7 lines] > > Any suggestions? Hm? You're expecting Vista to work reliably in any way? Pretty unjustified... Do you feel better now? Good. >> Hi, >> [quoted text clipped - 10 lines] > Hm? You're expecting Vista to work reliably in any way? Pretty > unjustified... Stephen Quist wrote: [broken quoting corrected] >> Hm?

All worlds knows (correctly) that Vista is utterly broken, so replacing it with a serious operating system is likely to solve such random errors, or at least giving a chance to diagnose the actual cause without mangling it with these random errors. You must work for Microsoft. What you say is true but completely useless. Did it occur to you that I put Vista in the VM because it's on Vista that I need to get something to work? > Stephen Quist wrote: [broken quoting corrected] > [quoted text clipped - 8 lines] > random errors, or at least giving a chance to diagnose the actual cause > without mangling it with these random errors. > You must work for Microsoft.

Most people use VMs to test out other OSes before installing them on the real machine, without any actual need. Did you install the virtual machine additions? > Hi, > [quoted text clipped - 11 lines] > > steve Yes, I did. The fact that I can see the local network means the NIC is working. The DNS and gateway settings come from the DHCP server. They look right. I'm kind of stumped. Could it be a firewall issue? If so, which one?

If so, >which one? The Vista one or the XP one? Check the firewall on the host, occasionally this will block traffic from the VM. Can you ping the gateway and DNS servers?

How can the firewall on the *host* block a virtual machine that uses the host hardware NIC? All previous discussions have pointed out that the VPC network service goes below any host software and passes traffic "under the hood" to the guest system if the guest's MAC address is used. How can now suddenly the opposite be true???? Bo Berglund It can happen, some of the firewalls work "under the hood" too. SignatureBob Comer >>>Yes, I did.

Because the virtual machine doesn't access the host's NIC directly, but goes through all the emulation, and the emulation itself simply calls into the NDIS stack. Depending on where the firewall's filter driver sits in the stack, it may apply its policies to such traffic as well. Well, the story got a little more complicated (or less, depending on your perspective). I could ping the gateway and DNS servers. With more investigation I found I could access sites such as Google.com and cnn.com. It's microsoft.com that it won't connect to! Feh. Steve >>Yes, I did.

Now I'm figuring out what settings I must put in the firewall (Trend Micro Internet Security 2008). Or does someone know how to configure the firewall on the host pc.

Obviously works as designed: messing up the network. So where's your problem? |
