It's a Management utility almost certainly loaded by your company for remote administration.
Your post poses more questions than answers.
Do you wish to use your laptop for both your company network and your own?
If you do, you would probably be better off adding a new user to the machine, leaving your present configuration for company work, and configuring the new user for your home network.
If not, (and either way anyway) you have to look at how the machine is trying to join the network.
By far the easiest method with your router, is to use the router as a DHCP server and configure your home machines to obtain a network address from the server (router). What you don't want, is more than one DHCP server, so if one of your machines are configured as such, the router should have a defined address range list, to listen out for, and should not be set as a server.
Many "Access Denied" errors are caused by Firewalls, and these should all be turned off for the duration of the troubleshooting period. Once the network is working correctly, they can be reinstated. I am not familiar with your router, but the chances are, it has its own Firewall anyway.
If you open up a Command Prompt on one of the machines using the network, and type the command;
ipconfig /all [enter]
(note the space between the g and /)
You will now see some information.
1. Is DHCP enabled?
2. IP Address (this is the machines address)
3. Subnet Mask
4. Default Gateway (this should be your routers address)
5. DHCP Server (this will reveal where DHCP is initiated - if it is active as in 1 above)
The rest is not relevant at this time.
Now do the same on your problem laptop and check that the IP address is in the same range (not an identical address) and the Subnet is the same. Are points 4 and 5 the same too?
If you can come back with some answers to these questions, maybe we can move forward towards a resolution.
