Computer will not recognise any new network.

OK. I no u guys are good, so please help.
I cannot set up a network place in a new sony vaio laptop. When i use network setup wizard it asks all the right questions. The laptop is seen by other computers on the network but does not allow access. When i veiw workgroup computers from the laptop it does not even see itself. I can ping other computers from the laptop but i cannot ping the laptop itself. I can ping the default gateway. I have tried changing the ip address but to no avail.
I have tried copying the exact settings of everything on another new vaio that works on the network but this laptop will not recognise any workgroups at all. I do get internet access from it. I am now desperate and running out of time. This is urgent!!!!

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Is it working? If so, why the "C" grade?
selecterAuthor Commented:
I have seen a lot of your replies and they have been indepth and given good info. The machine is working now but it came from link you set. As this was not your info but that of someone else, i think c grade is adequate. you do give good advice and if i recieve advice from you directly, then i would not have a problem giving a higher grade. 500 points for a redirection is quite a coo don't you think?
"Ask 10 Experts this question, and you'll get 10 different answers. One thing is certain: Grading at Experts Exchange is NOT like school. Here's what EE says:

Although we use an A-D scale here at Experts Exchange, it works differently than, say, school grades. If one or more Experts' proposals are accepted as answers, they should usually be given an A or B grade, since they have taken the time to provide you with a working solution. If a possible solution is incomplete - ask for clarification or details before accepting the answer and grading it. People should not be given lower grades because of incorrect grammar or because you just accepted their answer or comment to close the question. Keep in mind, your question and any follow-up comments should be focused so that there can be a specific answer. The following is a good guideline to follow when grading:

A: The Expert(s) either provided you with a thorough answer or they provided you with a link to information that thoroughly answered your question. An "A" can also be given to any answer that you found informative or enlightening beyond the direct question that you asked.
B: The Expert(s) provided an acceptable solution, or a link to an acceptable solution, that you were able to use, although you may have needed a bit more information to complete the task.
C: Because Experts' reliability are often judged by their grading records, many Experts would like the opportunity to clarify if you have questions about their solutions. If you have given the Expert(s) ample time to respond to your clarification posts and you have responded to each of their posts providing requested information; or if the answers, after clarification, lack finality or do not completely address the issue presented, then a "C" grade is an option. You also have the option here of just asking Community Support to delete the question.
Remember, the Expert helping you today is probably going to be helping you next time you post a question. Give them a fair chance to earn an 'Excellent!' grade and they'll provide you with some amazing support. It's also true that a "C" is the lowest grade you can give, and the Experts know that -- so use it judiciously"
