Shoot. I didn't use VMware much, but maybe I'll know the answer to your problems.

Add an entry for your Solaris host in the form of
ip_address hostname

to C:\WINDOWS\system32\drivers\etc\hosts on your Windows machine.

On Solaris 10 at least, /etc/mnttab is now a separate filesystem unto itself. This allows the kernel to ensure that it is never out of date.

$ uname -a
SunOS geo-support1 5.10 Generic_127111-10 sun4u sparc SUNW,Sun-Blade-1000
$ df -k /etc/mnttab
Filesystem            kbytes    used   avail capacity  Mounted on
mnttab                     0       0       0     0%    /etc/mnttab

You can list the contents of /etc/mnttab by issuing "mount" with no arguments. Note that /etc/mnttab is included...
$ mount

How can I get my tape drive to work after deleting my etc folder?
