Windows 7: How do I remove unwanted homegroup?

There's a timing issue here; The Computer Browser service only renews its view of the workgroup every 12 minutes.
If you change the Computer Name, then you need to wait 12 minutes to see it in the other systems by the new name.
View Microsoft Network can expand [+] Workgroup and the list of active computers will be seen; this is where the name change occurs.

If you attempt \\newcomputerName\shareName and find you cant access the system, this is also related.

Hi bertilak,

Its nice to know everything worked out well. And, yes either release/renew or power cycle of router provides a new IP address until and unless you have not made a static IP address.

Feel free to to reach out to us for any future queries.

sort of.
There are two ip addresses when you have a router:
  1. the dhcp address assigned the PC from your router - - aka the LAN(private) address
  2. the public ip address assigned by your ISP to the WAN(public) ip address
From your PC, a /release, /renew will only go as far as your router, leaving you with the same public address.

To attempt a new public ip address, you need to use the facilities within your router to perform the
/release, /renew sequence. You should also know that due to the existing LEASE, you may see no change
and just get the existing ip again. To ensure a new ip address, you must power off the router until the
lease period has expired.

But the question was related to the DHCP server on the router? Not the public IP address assigned by the ISPs router(s)

Hi jobeard,

I completly agree with you release/renew would only assign new LAN IP address but would not change the Public or WAN IP address.

However, some routers like mine have an option to release the WAN IP from the router configuration page and it provides new WAN IP address whenever I use it.

I understand it would also depends on ISP as well whether we would get a new WAN IP address or not.

Thanks for the useful information.

True though some ISPs will statically assign you a public address and in those cases nothing will change that from the router side. All your router knows is to send traffic it does not have a route for in its routing table to the WAN interface (Default Route - 0.0.0.0 = All traffic)

An example of mine is below however I set the IP address:
