Limited connectivity to the server

SBS 2008 Standard with eight Lenovo clients. All of them are on a domain, and seven of the eight can access the server with no issues. These are all Win 7 Pro 64-bit. In network, all of the seven can see all of the other computers.  

There is one computer that can only see itself and one of the NAS. When I do an ipconfig /all,
everything checks out especially DNS. I checked the Ethernet cables, although I can't definitely say they are working. The NIC card seems to be working, although the same caveat.

But, the weird thing is I can access SharePoint and access billing software database, but I can't access one of the other programs. But, that is a notoriously difficult program to connect to SQL 2005. UNC works as I can uses the address \\server\installs\ and open the program easily. I have rebooted the computer and ran troubleshooting on the NIC card. I also disabled and enabled the NIC card. Silly, because I don't know how it could work one minute and not the next.

So, in summary, it can only "see" itself and one of the Network Attached  Storage units, yet a couple of programs which rely on connectivity to the server can find the databases they use. UNC works but one program doesn't. SharePoint does.

I have no idea. Thanks for any help.

Check the windows firewall, you may need to open/allow port 1433 for SQL ..

I am a bit confused. UNC works. SharePoint works. Your billing software works. And the one thing you listed as not working is a program that you've had enough other problems with that you say it is notorious...so may not be network related at all.

So what *doesn't* work? All you say is that the machine doesn't "see" other computers, but clearly it sees the file services (UNC) and web services (SharePoint) so.....perhaps if you were a little more specific with the symptom(s) we could help more. As far as I can tell from your description, nothing is wrong...

Thanks Cliff. I appreciate your help. But, it is difficult to manage the computer when I can't click on Server to get t the server. I am certainly not going to use UNC every time I need to get to the D:\ drive. Plus, I need to scan the 30 folders or so to see what I need.

There has to be something wrong when all the computers aren't listed.

Thanks Iruiz52 as well.

10 Tips to Protect Your Business from Ransomware

Sorry, if I sounded like I snapped at you. I know you are trying to help. I just don't know how to be more specific. And, I shouldn't make the other program that bad as far as connecting.

Again, you haven't described the specific symptom(s). I'm not saying there is nothing wrong. I am saying that you've given *no* specific description of the problem. I get the impression, especially with your follow-up reply, that you are making assumptions about how something should work but haven't bothered to tell is which "something" isn't working as you expect.

How is the one machine behaving differently than the others??

The best way to be more specific is to describe *exactly* what you are trying to do. Don't make assumptions. List the program that you are launching. The steps you are clicking through on. And what happens on one computer (that works) vs the computer that doesn't.

Right now, for all I know (as an extreme example) ...when you say your computer can't see anything, you could be having a webcam problem. And based on the lack of information, that problem could be a broken webcam, a broken driver, or just a poor choice in the program you are trying to use to access the webcam.

Now clearly I can guess you mean something else entirely. More realistic and more network related. But I cannot right now tell you if you ware talking about strictly a SQL problem (after all you mentioned it a few times), a browsing the internet problem, or some other issue. All you've said is you can't "see" things.....IE? Firefox? SQL Browser? ....that is how you need to be more specific.

All of my other clients show all of the computers. Shouldn't they all look like this:


Network computers
instead of only the top two?

I didn't say it couldn't see anything. I said it couldn't see the other computers, as in it can't see the computers above.

I apologize. I am trying. I am talking about a network problem I should be able to have the server icon show up in my network windows.

Thank you for your help. I will look at the firewall and, otherwise, I will try to fix it myself. Again, I'm sorry I wasn't specific.

Okay. That is a feature called sharing and discovery. It uses a combination of RPC and SMB to discover other machines. You have to configure it. The various settings and firewall rules are documented here:
