A personal computer is a general-purpose computer whose size, capabilities and price make it useful for individuals, and is intended to be operated directly by an end-user with no intervening computer time-sharing models that allowed systems to be used by many people, usually at the same time. Personal computers may be connected to a local area network (LAN), either by a cable or a wireless connection, and through that to the Internet. A personal computer may be a laptop computer or a desktop computer running an operating system such as Windows, Linux or Macintosh OS.

We have a client who share data between 2 computers. PC2 connects to PC1 for shared data and some software.

Intermittently, PC2 loses connection to PC1. The share is setup as \\PC1\ Data. When we dial in, we can ping the IP address but not the PC name.

More often than not I will add a shortcut using the IP Address and then the the original shortcut using the PC name will then work. We have tried setting the shortcuts using the IP address but this had the same issue but in reverse.

I have set PC1 to static, checked Computer Browser service and UPNP are set to auto on both. Disabled all advanced sharing settings, reinstalled SMB from features and then Enabled all advanced sharing. It will work for a period of time and then lose connection again.

Any suggestions?

We installed Exchange Management tools CU6 version  on my  PC. I removed it from my PC in order to install cu10. I am now unable to install CU10 version of Mgmt tools.
It error out at the prerequisite check stage, the PC has met the requirement in the CU6 installation and also  .Net 4.7.1 is in the PC.
I ran setup /role:mt /IAcceptExchangeserverlicenseterms. it was copying the file then checking the prerequisites and error out.
Looking for a bit of advice guys.. I have a asus ZX270 MB, i7 processor all is running great.  I am using 2 monitors 1-hdmi and 1-display port, I have no graphics card installed. I want to be able to run, say a video on the tv and  work on the pc on the monitor.  since I only have one graphics source I don't think I can do it.  But the question is this-  I have a usb c port could I use this to stream to the tv while running the monitor from the display port.  My own feeling is no, since there is still only one source but I am no expert so I thought I would ask you guys if this is possible.
I am having an issue of uninstalling the Exchange management tools.
It has completed the pre-checking part and failed at stopping services.
I tired via CMD at BIN dir as well as through control panel.
Error in the log as below.

I have Dell Optiplex 7050 and has Window10 running on this pc. We use BitLocker for disk encryption. After I have  BitLocker encryption running and reboot It asks BitLocker recovery key.  Then I found the following steps seems to work:

Deactivate the TPMAutoProvisioning within Windows via the Administrator PowerShell:
1. Right click on the Start menu.
2. Type powershell, right click to run as admin
3. Type the command Disable-TpmAutoProvisioning and press Enter and make sure autoprovisioning is disabled.

Delete the TPM within the BIOS using the Clear option :
1. Restart the system and go to BIOS setup
2. Select "Security".
3. Click on "TPM Security".
4. Choose to Clear the TPM and then click yes to removing all keys from the TPM. (TPM will need to remain active).
5. Then exit and reboot into BIOS again to verify that the TPM is still seen as active.
6. Exit and reboot into the Window.

Activate the TPMAutoProvisioning again with the following PowerShell operation:
1. Right click on the Start menu.
2. type powershell and right click to run as admin
3. Type the command Enable-TpmAutoProvisioning and press Enter.

Under the tpm.msc make sure TPM management provided TPM status as ready to use, with reduced functionality.T hen
1. Turn OFF Bitlocker. Wait for  the hard drive to decrypt.
2. Turn ON Bitlocker. Reboot and no more ask Recovery Key.

It seems work after restarting the pc several times and it did not ask Bitlocker key until I shut it down…

I've got a client who is having a VOIP issue (ongoing for several months).  Here are the facts:

1. Very small client: 4 users on a local domain, Windows PCs and a Server 2008R2.
2. VOIP phone system using same router as computer network.
3. Two phones work solidly.  Two are intermittent.  Tried varieties of plugging in phones, including directly into LAN ports on router instead of the network switch.
4. Intermittent symptoms are: 50% of the time a caller calls the number and gets either a fast busy signal, or "your call cannot be completed as dialed".  Sometimes the caller goes directly to voicemail even though the phone is not in use.
5. One of the phones has been replaced, as an experiment. Used to be a SNOM 320, now an Aastra model.
6. On the working phones, unplugging the phone on the network results in the caller getting voicemail.
7. On the intermittent phones, unplugging the phone typically results in the caller getting a fast busy signal (even at times when the phone seems to be working).
8. At a time when a phone was not working, I ran a continuous ping test to the phone from a computer on the LAN, and it never dropped out once.
9. Before the problems occurred, they enjoyed excellent service on this LAN hardware for some number of years.

The VOIP company is saying that the problem is either the switch or the router, though there are never any detectable problems on the network (there is a Windows 2008R2 server …
Is there a device that I can buy that will diagnose a motherboard?  I've done the paperclip test on the PSU, so its ok.  I've replaced the cmos battery, reseated everything.  PC won't POST, so I need a hardware tool to diagnose why?  Ideas?
I have an LGA 1366 socket mobo GA-x58A-UD3R, full tower, and an i7 cpu I built 8 years ago.  I tried to boot up today, and it wouldn't even display BIOS, nothing.  Fans work, drives work, so I think the mobo is dead.  So now I have to either keep the same or upgrade (I have a full tower with 4 drives & 2 DVDs).  My sound and sound cards are all PCIe.  So  I have 3 choices:  Replace mobo; upgrade mobo (keep as much hardware as possible); run over PC with my car and buy a new PC.  I built the PC and its been great for 8 years.  Looking for the most cost effective thing to do and I've been out of the process for a while and don't know what the newest sockets are and whats interchangeable.  Any thoughts would be helpful.
I have a client with an older consumer style HP inkjet printer (USB).  I'm not on site and I can't recall the model (might be a Deskjet).

Strangely, one user account on the Windows 7 PC prints fine.  Another user account gives a print error.  Both user accounts are Admin accounts.

I removed the printer from the printers window in Control Panel, then unplugged the USB cable.  In the user account that doesn't work, plugging in the USB cable immediately gives an "unrecognized device" error.  If I switch to the account that can print, plugging it in results in the driver installer wizard.

I've never seen this kind of behavior before.  Anyone have any idea?

Win7 source pc unable to find the WDS server from the Image Capture Wizard.  I receive an error message "network location could not be reached".  I can ping the WDS server (Windows 2008 R2) ip and the source pc non-stop.  The WDS boot-up screen shows up on the source PC so I have to believe that it is communicating with the WDS server.  I've updated the drivers in the capture image and added the registry entry "maximumBlockSize" (set to match the value of the Cisco 2960 switch).

After all that, still can't get the WDS server to capture the image from the source PC.  Any help in resolving this would be greatly appreciated!
Hi Guys,

I have an interesting issue, after replacing a faulty HDD and allowing the RAID to rebuild successfully, a single user mailbox acted weirdly and i had to investigate and follow the usual routes and causes. Ultimately nothing worked an i created a new user in AD with a new mailbox account which was working correctly,

The disconnected mailbox will not reconnect to any other user account and i am afraid it may be corrupted, but before i pull the plug i thought of asking for help. Following is a shortened version of the message i got on the user pc, in hindsight i should have gone offline end exported all to PST but........
"Your mailbox has been temporarily moved to ... A temporary mailbox exists, but might not have all of your previous data. You can connect to the temporary mailbox or work offline with all of you"

Any solutions or suggestions or even is there a fee tool to convert an ost to pst??

We have a Windows 10 Pro PC that is having a boot up problem.

"0% complete"

"For more information about this issue and possible fixes, visit https://www.windows.com/stopcode"

"If you call a support person, give them this info:

This PC has been stuck on 0% for a few hours.

What do we need to do to fix this error?

I run Windows 10 on my PC, and have the latest version of iTunes which I use to sync my Outlook to my iPhone 6 Plus.  A few days ago I got a new replacement phone (also a 6 Plus).  When I went to synchronize through iTunes the phone was found, and seemed to sync fine.  All of my Outlook changes were synced to the phone, but none of my Playlists or songs were.  I checked all the settings for iTunes (which were the same as what I've always used in the past), with the desired playlists marked for synchronizing.  I also checked the playlists in iTunes and all the songs were still there.  But after syncing none of the playlists or songs had synced.  I can't figure out why.  Can you help?


For some reason my home triple monitor setup isn't working correctly. The normal setup works fine but when I try to configure nvidia surround for gaming the middle montor, which is a different brand but the same size, has black bars on either side. I have never set up a PC to do this and was wondering what was going on.

I am running an i7 8700k, 32 GB mem, and a GTX 1080 ti so it should support it without issue.

My monitors are

From left to right.

Samsung 27in 1080p 60hz , Dell 27 in 1440p 144hz, and another samsung 27in 1080p.

The dell is the one with the issue.
I have an application running on several customers PCs (Delphi XE2 developed).
The application sometimes access a FTP server (hosted by OVH, very reliable)  to download some files.
It works fine on all customer's PCs, ... except, since a couple a days, on one of them.
I could verify that the connection is correctly established but the "get" results in the following error :
Socket error 10054, connection reset by peer
I have asked the customer to retry, after disabling his anti-virus and firewall (I could not very that yet) but the error is the same
Microsoft Photos keeps popping up when I connect my iPhone to the PC.
How can I stop it from doing it?

All our PCs are set to sleep after 20 min.
Sometimes I need ot log in remotely to one of them so I remote into our server (which is always on).
If I'm lucky I can RDP from there into the workstation, but in most of the cases I cannot.
We tried configuring the PC BIOS + Windows for wake on lan, but it's not reliable.

Any suggestions?

Hi all,
Recently my internet connection  has been upgraded by provider from 100mbs to 800mbps snd they have confirmed I must have the speed near to 800mbps, but what comes to my surprise was the connection never had that much of speed, the fastest I have ever reached only up to 200mbps and never cross this.
So I decided to call the technician to inspect internet  line and etc, they did not found out any wrong and when the guys do some test with his own laptop he managed to get > 800mbps  that speed.
my questions is that what I can do now in order o improves my speed ? at least  500mbps if possible although I have been provided with 800mbps.

I'm running my machine with windows 10, 64 bits with 16GB memory installed and this pc has connection to corporate networks via vpn which I rare use them except when needed.of course I have antivirus installed and I never have any intention to run tsi machine without protection.
