Network IP Wrong

We're running a windows domain environment with three domain controllers.  If I try to rdp to a laptop on the domain by its host name I'm connected to a different host than I should be.  I'm thinking the host name is pointing to an ip which is assigned to another machine.   How can I correct this ?  We're also running cisco wireless which is handing out IP's to the laptops ...

Thanks ...

1. Check the IP address in your HOSTS file (c:\windows\system32\drivers\etc\hosts to see if it is pointing to the wrong place.

2. Try connecting to the machine by IP address.

3. Run TCP/IP Reset and DNS Flush.

Open cmd.exe with Run as Administrator
Then  netsh int ip reset c:\resetlog.txt
Also, ipconfig /flushdns followed by net stop dnscache followed by net start dnscache
Then restart the computer

Am I performing all these tasks on the server I'm trying to rdp from or the client ?  I can't connect via IP to the laptop as I do not know the ip and a ping resolves to a different machine .....

Is your wireless used to connect these machines on the same subnet as you expect ?

You would appear to have a DNS or HOSTS issue as that is where direction and re-direction takes place.

On your DNS server look in the Forward Lookup Zone for your DNS domain.  Check that the hostname you're trying to RDP to is pointing at the IP you expect it to be pointing at.  If they are, it's likely to be a hosts file issue.  If not, it's probably DHCP not updating DNS correctly.

By Cisco wireless do you mean Meraki Cisco?
if you have it handling the DHCP it will have nothing to do with your internal wired network thus causing you your "issue" and only by coincidence the default addresses look the same.
Set your DHCP/DNS for your wireless clients to your own DHCP server unless you are taking advantage of the walled garden then in which case you shouldn't be RDP'ing to anything in it.
If you are not talking about Meraki Cisco
Do the wireless clients have any issues resolving external addresses?
