Phantom computer on network
I have 13 pc's networked in house. All use regular TCP-IP with no homegoup allowed All but one of them is running Win7 in some flavour, e.g. 32 or 64 bit. They all behave fine and network more or less works as expected A week or so ago, as I've often had occassion to do, I redid someone's pc. In this case I did a reinstall of Win7 Pro on a fairly fancy pc, an Athlon 6 core "something" running in the 3.5Gz range with 16 Gb memory and in total 5 hard disks in unit. I did take out the PCI-IDE card which dropped the hd number down to 4, all SATA. After install which went very smoothly given Windows knew about every piece of hardware (clean device manager, a surprise), I connected network cable and started updating it, e.g. Windows Update. I gave the pc the name AMD-SEPCORE as it showed 6 cpu's in device manager. All went well and I took pc back to owner (which is a different story : () Problem is now when viewing Workgroup pc's an AMD-SEPCORE pc shows up under a second "Computer" listing. You can do nothing basiclly with the item. Now I did nothing more with that pc than I have with literally a hundred others over the years. None of the others have persisted in this way. Anyone with any insight and specifically how can I get rid of this phantom pc? |

Anyone with any insight and specifically how can I get rid of this phantom pc? The network browser protocol "remembers" machines that have just shutdown and powered off. It may take some period of time, or followup event, to clear it. For example, if another computer acquires that IP address from DHCP on your LAN, then the name will undoubtedly be lost. On a proper domain, a server keeps track of stuff and is a "boss". Whereas on a home LAN, the NetBIOS Browser election process, nominates a standin for a domain controller, and that machine then provides a list of machines in the neighborhood. That's sort of the basic idea. Elements of that protocol, have a ten or fifteen minute time constant (the events are given a different color in Wireshark, making it easier to see them). Browser elections don't occur in a microsecond, or get updated once a second. This is part of the reason that network state information seems to change so slowly. ******* You should take a screenshot of what you're seeing, and share it with us. If you're seeing a separate entry that is graphically separated from where those are normally displayed. Perhaps the location of the orphan will jog someones memory on the topic. As an alternative, have a look at the pictures here, and see if yours is similar. https://blogs.technet.microsoft.com/...ork-resources/ One of the protocols on Windows 7, exists mainly to draw the ball and stick picture of Network Map. That blog entry doesn't include a picture of that ball and stick model, to demonstrate. You can see a Network Map example here. At one time, you had to install SSDP as a separate step to enable stuff like this. https://msdn.microsoft.com/en-us/library/cc505886.aspx https://i-msdn.sec.s-msft.com/dynimg/IC165996.png Paul |

There's still a "Computers" catagory with the phantom pc listed on all the pcs in the network. |

There's still a "Computers" catagory with the phantom pc listed on all the pcs in the network. You could try nbtscan and see what it shows. http://al.howardknight.net/msgid.cgi...nt-email.me%3E http://www.unixwiz.net/tools/nbtscan.html http://www.unixwiz.net/tools/nbtscan-1.0.35.exe nbtscan 192.168.1.0/24 The idea being, to see if at some level, the list is "normal". You'll need to adjust that address and netmask, for the particulars of your setup. ******* Some of the entries in the Explorer display, can be removed by editing certain CLSIDs in the Registry. There was discussion some time back, about the removal of Library entries for example. This isn't the best article on the topic, just the first one I got in a search. Using a CLSID from here, I found a bigger list of CLSIDs. https://answers.microsoft.com/en-us/...e-cea9c6af8b2e (A list of other CLSIDs.) https://www.tenforums.com/tutorials/...dows-10-a.html There's no listing there for Computers that I can see. And I don't know how many areas of the screen are controlled by stuff like that. Or if that's the problem. The Libraries removal, was removing "Libraries" from the Explorer left hand sidebar. Paul |

Whereas on a home LAN, the NetBIOS Browser election process, nominates a standin for a domain controller, and that machine then provides a list of machines in the neighborhood. That's sort of the basic idea. No the "extra" icon is unique and only listed under catagory "Computers" and not the catagory "Computer". It appears the item is somehow connected to wireless device. I do remember using a USB wireless dongle first on the before mentioned pc to find a driver for it's onboard nic so I assume that's where the name of the entry came from. What I don't understand is why it's persisting, days now. My laptops all use wireless and they don't stick around after being shutdown nor have any desktop pc that I've used the wireless dongle on before. It also appears I'm somewhat stymied in fact pc doesn't have any wireless so dialog boxes don't appear (I can't edit any profile whatever that is as an example) because service isn't running kind of things. Right clicking icon brings three choices, Configure, Create Shortcut and Properties. Configure gives an error message "Windows does not have any network profiles for this device to use" and I can click on a "Manage Wireless Network" which brings up an erro box informing me wireless isn't running so no go there. The displayed profiles dialog is empty of any entries. Model # is 1.0. Properties gives me a "... Webpage unavailable" but does give me a Unigue id and a Mac address (that doesn't appear right 00:16:44:99:23:f8) and no IP address. I've been leaving the network dialog open while writing this and have noticed the damn icon has appred and disappeared now three times, wtf is going on with that??? It disappeared and a refresh brought it back? |
