Firewall blocking access and wont allow me to map a network drive. tells me my modem has an error yet I can do anything across the network I want other than that.

I have been trying to get a mapped network drive to work. I have permissions I am certain.  I can get to everything from a second dell machine similar to mine. The problem:

The errors are below when I open them from my personal PC. I will not be able to use the other similar Dell as it is not mine but another consultant who will be on a project next week. I have to either get mine working or be forced to purchase one that will work. Your help is greatly appreciated. I was not expecting to have to pay 2k to come to work but I will if I have to. I do not have it honestly.

So when I try to map the network drive on my machine you see the FirstMapDriveError
Then after cancelling that message you see the second error which displays the port issue.( I do not know how to troubleshoot that at all)
Third is the Modem error the message that the firewall displays when I launch it. All networking access to databases and applications behind the firewall work just not the "Map the Network Drive". We have checked the path we are sure of that as well. Any advise is greatly appreciated. Thank you.

I think the port in question is 6400 but I am not certain
How do I close all the programs ...should I use the msconfig ...maybe using Diagnostic Startup where basic devices and services are loaded.
what tunnel application are you referring to. STUNNEL ..?  It starts up and runs automatically or are you referring to something else?

I do not know how to open all possible ports between the firewall and test connection. But I may not need it if I can get the answer through #1 answer.

Thank you for the effort you made here.

Once I find it I assume I just uninstall or disable it. Why does it say modem problem..?

modem problem...i think it is just the error code associated by the application. assuming you are using a ethernet based connecitvity...

I was using Wireless and Local cable connection. I disabled the wireless for the faster cable.

I have included the screenshot for the Task Manager. I did uninstall Skype and disabled GoToMeeting and a few others.

What is netsat -ano
Is that a built in function or a file I need to download and install?

Any tricks to finding updaters and chats. I do not do chats but I do have GoToMeeting installed...? I exited out the system and got that closed among other things.
I just ran Netstat -ano and I do not know what I am doing or looking for here can you help...?

keshavj22: "if you can find the port, then you can do a netsat -ano to figure out which process is using the port, you will see a pid which you can then look-up in the task manager."

What is a pid and where do i find it in task manager?...Wait I found it. So if I find a number in Task Mgr PID that matches a PID in the Netstat -ano run I have found the culprit......?
I can then stop the process and in all likely hood resolve the port issue.....?

Yes I am running Stunnel and TunnelServer but would not know how to check to see if they are conflicting...?
I had figured out thankfully finding the PID stuff. I matched about ten numbers under the Netstat with the PIDs in task manager.
Port     -     Name
1996   -     mqsvc
2000   -    svchost      there are lots of other ports using this
3832   -     alg.exe
952     -     jqs.exe    Java QuickStart
2812    -    STunnel
3208    -    TunnelServer
1948   -     cvpnd
5920    -     mstsc   Remote desktop
1908   -   snmp
1220   -   lsass

Does this help these are both in netstat and in TM



STunnel is using                      port        2812
TunnelServer is using these   port        3208, 4524, 4532

 Were you thinking that the ports would be the same....that kind of a conflict or that the configuration of them would be in conflict....?
It is working thanks to your tips.
