Operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the disk, and controlling peripheral devices such as disk drives and printers. For large systems, the operating system makes sure that different programs and users running at the same time do not interfere with each other. The operating system is also responsible for security, ensuring that unauthorized users do not access the system. Operating systems provide a software platform on top of which other programs, called application programs, can run.

I recently updated a sync computer batch file from xcopy to robocopy.  This resolved some problems but I discovered that robocopy does not copy open files as xcopy did. Does anybody know of a copy routine that can run from a batch file that copies open files. The biggest problem is MS Word keeps files open in the background even after it is closed. It would be great if it has a copy version option (copy newer files to a new version number instead of overwriting the older file) and multi-thread capability. Free or low cost would also be good.

TIA

Hello Guys,

We are in process of upgrading one of the SQL Database from 2012 to 2016 version. The Database is moved/upgraded successfully to SQL 2016 version, now the problem is, the database is holding a Stored Proc which is taking longer time in the new version i.e on SQL 2016.  

On SQL 2012 stored proc will execute in 13 minutes where as on SQL 2016 it's taking 13 hours to complete. We been stuck with this since stored proc is having lot more dependencies to business.

We increased the memory , ram on the new server to 32 GB where as on old server it's 28 GB only, but both the servers are holding 2 cores only.

Old server OS is win 2008 and new box build with Win 2012.

We tried to find out blockings by running profiler when ever the stored proc runs but we haven't found any blockings ,this seems mysterious for us since no blockings, dead locks found.

Settings on SQL server are similar on both of the servers we haven't any odd.

Let us know if have any suggestions on how to solve this issue.

Quick help is really appreciated.

Thanks,
Venkat Kokulla

Hello everyone,
I would really need your help. My laptop for my work just stop working, here is the story:
the battery died and the computer shut down by itself, when i came back i turn it back on with power cord, enter my bios password and then black screen and the only thing i see in the top left corner: Error loading operating system.

So i try to boot on a Win XP cd and do F2 for repair, but when windows starts to start i have a blue screen telling me that the system need to shutdown for safety or something like that.
So ithought that it was a bad sector for booting or something like that, i boot using ultimate boot cd i can go in parted magic but i'm not sure what to do there. Any help would be appreciated.

And i know that i have some restore point on my system, i mean those restore point that you can usually use in windows to restore your system as an ulterior date, is there a way to restore those points without booting in windows???

Thanks

Hello
I have a program that does not seem to install on a Windows machine. Is there a way to check libraries or dependencies on a Windows application?
Perhaps I am missing one, but the OS is fully upgraded. Something like LDD in Linux.

Of course, I can ask the app dev but for future reference is there a way?

Hello.

I have been doing daily full backups on the server with OS Server 2012 R2 Standard and recently it has started to take very long to complete the backups.
The backups are scheduled for every night at 2100hrs and usually it completes between 0500hrs to 0700hrs but the last few days it has exceeded to almost 1000hrs and the last backup took around 24hours 15 mins causing the next schedule to fail.

The backups take long but complete successfully, i need to check what is the issue that the backups have started to delay that much.

Thank you.

I paid for and got some DELL support to reinstall a "fresh" copy of my Windows 2008 R2 OS after a virus essentially wiped out my network.  So, now I have to re-setup my network so that everything on the network connects and I can connect to the internet thru my SonicWALL device.  Problem for me is that I haven't had to do anything like this since 2013, when I first set up my server and I'm lost.  I can't get the basic network set up and this is, obviously, delaying my restoration of my Remote Desktop Setup (which I've worked on more recently, so I think if I can get the basic network up and running (and I mean "just the basics"), then I'll be able to move on and set up everything else I need to provide remote access to my application.  Being a programmer first and technician last, I just don't have the experience setting up networks, OS setup, etc. that other people in this forum have.  So the question at this point is how do I set up the server OS to connect to the rest of my network and the internet?

Hello, I have several Mac users that I need to install and trust a certificate on Mac OS High Serria, I don't have access to each user all at one time. I am not sure the best way to roll this certificate out to everyone I was thinking of creating a help doc and write out each step with screenshots and email the certificate and directions out to everyone, but wasn't sure if there was a better way. I just think it a few steps and I am sure I will hear some gripes about the steps but just don't know any other better way without doing it myself and time just doesn't permit that.  Any suggestions

Windows 10 machine that is no longer recognizing anything plug into USB.  It just shows them as other devices in device manager.  This all started from unplugging a USB printer, after that, everything went to that mode.  We tried plugging the printer back in, change what ports stuff is plugged into.  Not even the keyboard and mouse will work.  I tried reinstalling the Intel IME and I'm getting an error

Apple mail cannot connect to mail server.  We checked it on another mac with the same os and it connects.    It also connects with webmail so the password and user name are ok.
We turned ssl on and off and no difference.  We checked all the settings with another mac and they are 100% the same as we put on this one mac that is not working.

Still cant authorise the mail account.  check all settings and ports and they check ok.  Its a pop account.

Extend system drive on a 2008R2 server. From Google basically I found where everyone said it takes a third-party software to accomplish this task. This morning in a desire to practice using some of this software I set up a lab server 2008R2. Partitioned the first drive (300GB) into a 100 GB partition and a 200GB partition which I installed the OS to the first 100  GB partition. Installed some drivers, rebooted server. Formatted the 200GB partition copied a few files over to it and rebooted again. All looked good and was ready to download 3rd party software to begin testing.
However on a whim I went into Disk Management, deleted the second partition click on the C: (system) drive and the extend button was available. I extended the 100GB C: to a total of 300GB now.

Is this a fluke, am I missing something

Hello

I have to use for the very first time an Xen-server for an project but every time I tried to import an ovf file I get the message :

"Host CPU features reduced","The CPU feature level on host 'xen-server' has been reduced.","xen-server","Feb 14, 2018 9:10 AM",""
I don't get it
The Xen-server is installed on a computer with an Xeon processor over 16 Go of ram with 1 To of hard drive space so I don't understand I've update the Xen OS but the problem stays.
I've spend hours to search for the answer so if someone can please help it'll be great

Best regards.

My Os is win 10 prof 64 bit and I recently underwent a hacking and I am uncertain if the hacker had left any malware to come to live whenever the pc is booted on.  Hope if the Experts please take a look at the list of processes that are running and flag for me any potential threat that is still running.  Thank u. regards

I have inherited an ESXi environment this is minimally documented. I have been able to document location of the guest servers and the main hosts, but I have one remaining problem: I cannot identify which server is handling SRM. Some of the server are protected by SRM and this is causing me issues, as I need to expand some partitions, but can't because the servers are replicating using SRM. Os there a way to find the SRM on the network, either by looking at the host configuration or guest configuration?

I restored macOS 10.13.3 from current Time Machine backup, now some files cannot be located with Finder or Spotlight. Needed files were in UserName I used on daily basis.

I restored because logging into the other username made OS inaccessible - did not respond to any keystroke input.

Assuming they were on TM backup, how can I locate the files?

Question, I need to reinstall the OS on a Domain Controller Server in a small office. My question is if I name the server the same and give it the same ip. Will the pc's that are already joined to the domain just recognize it as the DC for AD?

Hi,
I am working on an Asus X751. When you press on the power button the laptop goes immediately into the BIOS every time. I have tried disabling safe boot,
removing the user and administrator passwords in the BIOS.
I have taken the laptop apart and replaced the CMOS battery but that din't help. I have removed the the main battery and the CMOS battery
and held the power button down for 30 seconds and that didn't help.
The laptop will only boot to the BIOS and not the splash screen or OS.
Any ideas?

mac OS 10.13.2 will not start after setup of 2nd User Account. 2nd account always available but never logged in.

After activating existing OS 2nd account, Mac will not start in Safe Mode or using Option + Command + P + R Keys

Progress Bar ran for > 1 hour without startup.

As last resort I have recent Acronis 2018 backup and current Time Machine disc

Best method to restore/restart OS without losing data?

My goal is, of course. to restore macOS without loss of Logins, data or program files.

W540 laptop with Windows 7, has given client problems with SSD failures.  Now the laptop is getting slower and random OS problems are occuring.  The current SSD is a 500GB Samsung EVO 850.  Firmware is current according to Magician, and only POR count is notable, but drive is showing in Good condition (Installed 1/27/17).  Yesterday the client attempted to reboot and the laptop shuts down...  Or so it seems, since they cannot turn power back on!  The fan is still running, and it seems hot.  The power indicators have all turned off.  It is connected to a dock, and no I have not tested off the dock.  Since the problem started, it is 5 for 5 on this reboot problem.  Holding the power button in for 5 seconds does kill the power, and allow the laptop to start.  A shutdown works properly.  Running Norton Security for AV.  End user reports no changes were made recently to the laptop in terms of software.  No Windows updates were installed in the last 2 weeks.  The laptop is shut off every night.  Everything works great on the dock in the office.  The only recent issues have been with off line (CSC) of mapped drive (Only user to share).  Able to repair when he returns to office, and it doesn't happen often when he is on the road.  I did run SFC and CHKDSK last night on the laptop.
