    VMware Workstation 7 - guest can not  connect to host computer

    kriemer Hot Shot

      My problem is compounded by the fact that I have upgraded to VMware 7 and added several virtual Win7 64 virtual machines at the same time so I don't know what (or which) is causing the problem.

       

      I have 2 host computers running WinXP 64 and VMware 7.  Firewalls are off on all computers, real and virtual, and antivirus software disabled to facilitate debugging.

       

       

       

      I can "see" Host A listed in my network of machines but I can not connect any virtual machine (Win XP 64 or Windows 7 64 ) to drives or folders in Host A.  Virtual machines of all flavors in Host B (as can Host B itself) can connect to drives and folders in either Host A or B computers.

       

       

       

      I am really confused as this is a new problem in a network that has otherwise worked without issue for a long time.

       

       

      Thanks

          No resolution but a little more detail.

           

           

          It appears that the problem is only between Host A and VMware.It appears that the problem is only between Host A and VMware.

           

           

          I can not connect from ANY VM on Host A to folders or drives on Host A; but I can connect to any other machines real or virtual on the network.  As I said previously, I can connect to Host A from any other machine on the network.  And any machine on the network can connect to any Host A virtual machine. 

           

           

          So far as I can see all the network setting of all the machines are the same.  The only difference I can see is that Host B VMware was installed as 6.5 the upgraded to v7; while Host A only had VMware v7 installed.

           

           

           

           

           

          Thanks again

            I've a similar problem:

             

             

            after upgrading to ws 7 none of the VMs are are able to connect to host when in bridged mode.

             

             

            The host is Win Xp sp3, tried with variuos different guests.

             

             

            When the ethernet is in NAT or Host only all works like expected.

             

             

            But when in bridged the guest cant see the host (no ping, nothing) and the host cans see the guest.

             

             

            The only problem is from Host to Guest, other pc in the net are working correctly with both host and guests.

              I'm glad to see I'm not alone with my problem (I hate that).

               

              I find that I have a similar problem with using any of the other

              network settings. I can now see Host A but other computers on the

              network can not connect to the virtual machine in Host A. The message

              is I lack permission to access.

               

              Do you have network setting that work?

               

               

               

              The real curiosity is if this is a VMware 7 "feature" then why do I not have the same or similar problems from Host B?

               

               

              Thanks for the response.

                This is definitely a problem/feature with VMware 7. 

                 

                I uninstalled version 7 from Host A and installed version 6 and I was able to connect my virtual machines with the Host.  I tried to reinstalled VMware 7 to see if it would still work but with no success, so I'm back to using VMware 6.5.   Of course this means that I can not run my Win 7 machines.

                 

                Why this is occurring on one Host and not the other is beyond my understanding.

                 

                If anyone has a better idea or a real solution please let me know.  

                 

                Regards

                  Check to make sure you are running the latest drivers for your NIC card on your Host.   Then try (temporarily) disabling any "task offload" or other "offload" setings for your Host's NIC card.

                    Can you peer share from any other real xp machine on your network to a Windows 7 share on your host.

                     

                     

                    In otherwords, can you ignore VMware all together and just connect an XP real machine to any share on your Windows 7 box?

                      The only peer share that I can not make is virtual machines to their host.  Host to VM's work, as as do VM's on other hosts.

                       

                      Strange ! ?

                        Drivers are all the latest.  How/where do I change NIC settings?

                         

                        Many thanks

                        PS,  I now notice this is exactly the same problem and subject of a Dec 1 posting.  Sorry for starting a new thread.

                          From your Desktop... Right Click Computer -> Manage -> Device Manager -> Network adapters -> right-click on your Network Adapter, properties -> Advanced Tab

                           

                          Look for entries that mention "offload". Each adapter will be different. For example, my Broadcom adapter has "Large Send Offload", "Proxy ARP offload", "Proxy NS Offload", and "TCP/UDP Checksum offload" settings that can be enabled or disabled.

                            Which AntiVirus program is installed that you disabled for testing?

                              I was using AVG v8.5 antivirus.  I have since uninstalled in an attempt to fix the issue.

                               

                              I will try disabling NIC "offload" settings next Monday (this is my wifes computer and I'm sure you can guess the rest).

                               

                              Not to be pedantic, but you mention that  this disabling would be temporary.  What if this does fix the problem, what am I giving up by maintaining the settings?

                                AVG should be ok.  Other AV's cause problems even if "disabled".

                                You would be giving up a tiny fraction of a percent of CPU time because your Host processor would be calcuating packet checksums instead of the NIC adapter.  Any difference would be unnoticable on a modern desktop computer.  

                                 

                                If a newer NIC driver becomes available you can always try enabling it again to see if the newer driver fixes it.  Same if a newer version of Workstation comes out.

                                  Right you were; that seems to have fixed it for me. 

                                   

                                  I had 2 Offload settings available; "Offload - CheckSum", and "Offload TCP_LargeSend".  A little bit of testing and I determined that I only needed to disable "Offload - CheckSum" to be able to connect to the host machine.  I figure in this case 1 is better than 2.

                                   

                                  Many thanks for your help and patience.

                                    Just out of curiosity, can you tell us what model NIC and what driver version is installed on your Host?
