i can only guess this problem has to be something with the host server itself.
the error hints at some buggy code "d:/build/ob/bora-422570/lib/pollDefault/pollDefault.c:3141" .... so its polling but failing? perhaps. i guess we'll never know since we cant see that c file.
another interesting thing is its saying to find the log file in the Appdata\Local\Temp\ folder but there is no sub vmware-**** folder.
i also tried another user name. same error. thats why i am confident the error is not the client nor the virtual machine. its the host software.
this is version 5.0.0 of the vsphere client.
there is no firewall or anything. this is very much a direct connection. it was working fine last night . ... i have changed absolutely nothing!
