Question: I've installed TFS 2008, but I can't seem to access the server. When I try to connect to it in Visual Studio, I can't. If I try by browser on a remote PC, I get a generic page cannot be displayed. On the server, I get a 403. Nothing was touched in IIS and the service is running as a Network Service. Any ideas?

Answer: 
try:

<http://localhost:8080/Services/V1.0/ServerStatus.asmx>. This will tell you if TFS is up and running. If you are getting anything else you need to look into IIS issues.
Add this to the cases for future users, as i had this issue on server 2016...

if your firewall allow only Domain and Private Network, it may not work on client. make sure you give public permission, if server network is set to public...

The error you may face:
`ERR_CONNECTION_TIMED_OUT`
for
`http://fserver:8080/tfs`
