User Credentials Cannot be used for local connections

Hi,

I am  creating several vms in the same vApp, say 6 vms in a vApp. One of my VM say VM1 has to communicate with the other 5. It attempts to get the systemDrive of the other 5 vms, using the network credentials, (IP\Username , Password). The problem is the VM1 is not able to getSystemDrive() of the first 2 vms that it is trying to access, but then it is able to access the rest of the 3. When VM1 attempts to access the first 2 Vms, it thows the exception "User Credentials Cannot be used for local connections", even though I am using network credentials.

If there was something wrong with the format of the credentials, it shouldn't be working for the other 3 vms as well, but its working after first two vms.

First I thought this might be due to some network inconsistency, but then I noticed, this was happening always, only the first two vms were not being accessed.

This seems very strange.

Please help.

Thanks,

Mansie
