TightVNC?

[mudcow007]

Anyone use TightVNC on here?

Just rolled it out across all clients (about 100 or so) Win7 clients are fine - after I created a rule for the F/W within ePO.

Win10 refuses to allow connection.

been onto a client an the VNCServer all looks happy an is set to allow connections

grr

Ive tried both normal viewer an java flavour too.

[P.]

nmap and see if its actually listening.

Port 5900 open?

[P.]

Indeed, unsure if it affects win10, but VNC should always have a password...

TCP 5900 should be open, you can download Zenmap to find out and run nmap -T4 -Pn IPADDRESS where IPADDRESS is the IP you want to connect to. This will list all ports that are open on the device.

Used to have problems with interactive desktop services as well if i remember correctly.

[mudcow007]

plot deepens further.

Windows firewall is off

Mcafee ePO firewall is on - i added the rule to open the port this morning, but its still closed.

Contacted Mcafee who have confirmed all looks good (firewall config) but i still cant access the port

As far as im aware there is no way of finding out if the clients have downloaded the new policies from the ePO.

grr

[P.]

Go to client, check its installed.

If not, that is why 5900 is closed.

Can you even use zenmap to check a single IP and see if ANY ports are showing.

[Loui5D]

telnet on that port?

[mudcow007]

[mudcow007]

Resmon confirms its listening on 5800 + 5900 with a firewall status of allowed an unrestricted

[P.]

[Rogerborg]

Shenanigans on that. Wireshark time.

Just lodged another support call to Mc-a-shaft

will update with results

[mudcow007]

Its definitely Mcafee

Disabled all services and I'm in like Flynn

now its figuring out what blocked me

[Pjay]

I had the very same problem, McAfee sees VNC as a threat. It was a while back so I forgot the exact fix, but it was down to telling McAfee to stop being a dick and leave VNC alone and then uninstalling vnc and reinstalling it.

Now that I think about it, tightvnc.com briefly got flagged by the ZScaler netcops as a malware site.
