UNIX for Dummies Questions & Answers

I have a virtual (vmware player) on which i have two small RHEL 6.7 servers and two win7pro 64 bit guest nodes running.

#virt. host issue: accessible remotely but difficulty joining domain.
The virtual host itself uses static IP and it is accessible. It is using win 7 pro 64 bit, as its host and runs the vmplayer on it. (Adding to domain is unsuccessful; in workgroup, the DC server can see this virt. host but virt. host could not reach it-Firewalls off)

#virtual guest nodes unreachable via ping/tracert
-I have 2 rhel 6.7 nodes X86 (64 bit) and two win 7 pro 64 bit are inaccessible either via dhcp or static IP (but would like to have static IP assigned so they could be reached w/o needing to land on the virtual host) but ping and tracert both fail as unreachable.
-default dhcp has network connection as work and has internet access, static IP assigned network connection as public and no internet
-Firewalls on virt. host, virt. nodes, my laptop are manually turned off.
- The guest nodes either static or dhcp assigned IP don't work even if i add them to my client laptops hosts file (windows>system32>drivers>etc>hosts) 'host unreachable'
-Static IP method used on other machines (independent of virt. host & virt. guest nodes) and they are reachable.
-Static IP that i am using are available.
-all nodes have complete hosts entries in their hosts file also. (windows>system32>drivers>etc>hosts) & /etc/hosts on rhel nodes.

#example:
independent node 10.20.18.130 reachable ping + tracert
virtual host node 10.20.18.132 reachable ping+tracert
virtual guest nodes 10.20.18.124 & 10.18.20.125 are not 'host unreachable'

I am out of ideas ... any suggestion is deeply appreciated. I would rate myself as novice networking person but have no qualm reading up.

Thank you for your time in advance

How are is your VMware Player networking configured at present?

What version of VMware Player?

Thank you for your time & interest in helping me.

VMware® Player
7.1.2 build-2780323 (non commercial use)
*I wanted to get the 'normal' ESX/hypervisor* install but since I am a newbie re. virtual setup and its requirements I opted to start with this player.
*Virtual host is on Windows 7 Professional, 64-bit 6.1.7601, Service Pack 1 with 49 GB and 8 processors

To be honest, I have not done any network adapter setting or configuration I accepted default. BTW, when i was setting this virtual host, i used static IP address (I am able to log in to it and of course use it but not been able to join it to our DC server. The DC server could ping this virtual host but virtual host could not but for now I could live with it, the issue is the virtual guest nodes as now i have to give direct admin access to the virtual host and ask user to start the virtual guest node...ideally I would just like to give direct access to virtual guest and not have to give admin access....sorry got long winded whining, LOL).

One thing i noticed the guest node is using DHCP by default but its gateway using an IP that is not what our DC or non static IP uses. But now I am not sure where to prescribe correct gateway when DHCP is used since there is no place I know where to correct it.

Sucks to be a newbie.

You have my sincere thanks.
