Server Software





A server is a computer program or a machine that waits for requests from other machines or software (clients) and responds to them. This architecture is called the client–server model. The clients may run on the same computer or may connect to the server over a network. The purpose of a server is to share data or hardware and software resources among clients. Typical computing servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers.

my pc suddenly goes blank screen. What should i do except restarting it?
Hi SFB Experts

as i understand from this link that in order to install SFB enterprise you have to have three front end servers in the pool

and in order to install SFB standard edition you have to use the built in MSSQL express inside SFB media

so what if i want to install only one front end server and use external MSSQL 2014 standard edition so technically this possible and such setup called standard or enterprise

i know front end server license is the same for stranded and enterprise only CALS play roll here but i want to know my setup is doable and under which category standard or enterprise

We have a installation with one
TFS2015 for building a webapplikation.
the deployment ist on a seperate webserver.
Now we have the problem that the TFS can't deploy because the Certificat of the webserver are expired.
We never deploy a certificat and we don't now who is the authority for the certificate
as workaround we are now using http for deploying the application.
I have been trying to setup a Hyper-V proof of concept system for quite some time. I am using a free Microsoft eBook titled "Deploying Hyper-V with Software Defined Storage & Networking" by Mitch Tulloch. There are probably other ways to do this, maybe better ways but this is the way I chose to do it. I have attached the eBook to this question for reference.

I am having an issue with configuring network virtualization. The steps used have you adding a couple of Gateway VMs through downloadable service templates from Microsoft. You deploy then configure these gateway VMs, create a configure a VM network and then deploy a couple of VMs on the compute host group to prove connectivity. Except the connectivity is not there. Neither VM can "see" outside its subnet as if the gateway is not doing its job.

I think the issue lies in the part where I am supposed to "configure your physical switch infrastructure to be able to route traffic into and out of this VM network and the respective virtual subnets" I am really not sure what this means.

I know this is really high-level but please ask any questions for the detail that matters to you.
What are some good step-by-step articles showing how to upgrade my below to 2016 since I have a small setup, plenty of backups, and can take everything down over the weekend if needed ?

Current Setup
 1. one PHYSICAL Windows 2012 R2 server
 2. five VIRTUAL Windows 2012 R2 HyperV servers
what's the name of that software I need to install on my HP ProLiant servers to manage them see my ILO info, install updates, upgrade my ILO, etc?  I have four Gen 8s that I need to install it on and I can't remember what to google.


I've been tasked to setup a Powerchute network shutdown for our vmware environment.

Does anybody have experiences setting up PowerChute network shutdown for vmware esxi hosts in HA cluster environment WITHOUT attaching to vcenter?
Is it possible?

We have three esxi hosts in HA configured and these are managed vcenter which is located on different LAN.
According to official documentaion, for HA environment, connecting to vcenter is recommended, but for our case, vcenter manages hundreds other esxi hosts in other countries, so I'm nervous to connect to vcenter.

We just need basic function that power chute provides such as proper shutdown of VMs in order.

Can someone advise how I should setup?

Thank you for your any help
I am receiving intermittent issues on a client server. After a while, users cannot access the internet or internal servers. Unfortunately, I am not on site and only have access to the logs as we need to restart the server before I can get there to minimise down time for all users.

Once the server is restarted, all users can access the internet/internal servers/share drives etc.

This has only come up over the couple of months randomly. Previously the DNS servers on the server had another IP which is the virtual server NIC (nic 2) and the TCP/IP V4 DNS had The 169.x.x.x has been removed and the has been changed to

When I open Dell OpenManage Server Administrator, it is correctly showing the inventory of the server, except for the physical and virtual disks on the machine. Instead, it is showing me the physical and virtual disks and RAID-5 array on a DIFFERENT machine. I have tried opening OMSA with localhost, the IP of this machine and its name, I have checked that NSlookup is only reporting the IP of this machine. Is there some way to force it to check the inventory again? I have uninstalled and reinstalled twice now.

I try to update System Center Configuration Manager to version 1706.
The status is "Applicable", but if you right click only have the option for "Show Status" other options are grayed out.
If you click Show Status, Download is in progress.
I already try:

1.delete the package under EasySetupPayload folder

2.delete SQL record by this command:
DELETE FROM dbo.CM_UpdatePackages WHERE PackageGuid = '0f11caa4-7f7f-454b-96d6-75f427d015ce'

3.Use CMUpdateReset.exe reset the package:
CMUpdateReset.exe -FDELETE -S -D CM_MYD -P 0f11caa4-7f7f-454b-96d6-75f427d015ce

After that the package was deleted on the Console, but when it try to download again, it stuck in the same spot.
We have newly configured AlwaysOn in SQL Server 2016. But we didn't added any DB to AG group (Just empty).
When i ping AG listerner i am not able to ping.

My understand is if we not add any DB to AG group, the listerner will not work.
Am i correct?  if not please correct.
I am now responsible for a very old 2003 environment with 2003 AD, 2003 Exchange and several 2003 servers.  I would like to do long term upgrade to AD2016 and on premises Exchange 2016.  Can the AD upgrade go directly to AD2016 (via additional new servers) and then a new Exchange 2016 server while still support existing 2003/2008/2012 servers with Win 7 end user devices ?  Would like to preserve existing domains (two) and upgrade the AD to 2016 first and then do an inplace/onsite migration from Exchange 2003 to Exchange 2016.

Lastly, there are still some Windows XP machines - I assume they must go ??
I have a search issue on my SharePoint 2013 farm. I not able to delete or create any search service application. When I looked at the ULS it keeps on saying the "SSA Did not match <guid> - <guid>"

We've had users complain of slowness of a HyperV running on a HP ProLiant DL380p Gen8 server. I can't see anything wrong with the HyperV itself, but the host server is showing strange issues.

The first thing I noticed is that one of the CPU threads is almost constantly pegged at 100% by System:

1 CPU thread at 100%
Digging deeper with Process Explorer I can see that is is ntoskrnl.exe that is that cause, but that is the system kernel, and so doesn't narrow it down by much:

Process explorer
Deeper still with Windows Performance Analyzer, the exact library in use is hal.dll and PSHED.dll:

My thinking was this is either a driver or hardware issue, based on the components involved here. So I start with some hardware checks using HP's System Management Homepage. First thing I notice is one of the 4 memory modules is reporting "degraded". I get the bad module removed and boot back up, and everything looks fine initially. But about an hour later a different CPU thread is now pegged back at 100%.

Ok, so maybe it's a driver or different device issue. No errors showing in device manager, so I went through and disabled as many non-critical devices as I could - no change.
I also updated the drivers for the HP iLO as it didn't seem properly installed - no change.

At this point I contacted HP Enterprise support. They downloaded their Active Health System logs, but didn't find any issues. They noted that …
I am using Oracle 9i database and PHP(5.6.33) for an application.

still error is not going.Please help me on so I can connect oracle database with PHP.
Hi Guys,

I am desperate for a solution!

We've setup an Exchange server 2016, transferred all the mailboxes across from Exch 2010 and everything was working just fine.
Abruptly the server could not access OWA or ECP and gave an error:

Bad Request - Invalid hostname
HTTP Error 400.  The request hostname is invalid.

Workstations were also unable to connect.

Upon troubleshooting I found all certificates on the server to be missing.
Creating a new request for both Godaddy and Selfsigned produced blank entries after import.

I recreated virtual directories, confirming virtual URL's, etc to no avail.
I called it a day, as we were under a lot of pressure and reloaded Exchange 2016 in a VM.

This time round I documented every step and followed the setup conservatively.
Fortunately the mailboxes were still available in the "broken" setup to be transferred.  This made me believe that the initial errors were IIS related.

The second-installation 2016 VM server (ecp, OWA, mapi) all was working fine and all mailboxes were transferred yesterday.

I made an IIS backup today "appcmd add backup xxx" to prevent an unrecoverable scenario as with the first 2016 installation.

About 30 minutes after the backup, ECP was broken yet Again!
BAD REQUEST - Invalid Hostname
HTTP Error 400.  The request hostname is invalid.

Needless to say did a couple of checks in EMC, including Default Website bindings in IIS, and did not find anything wrong ...

Setup required:
-1 x SQL 2017 standard server
-100 x ATM machines will be accessing the SQL server

I'm currently looking at two licensing models:
-Per core
-Server + CAL

Per core licensing:
If the SQL server has 6 cores, then I will need 3 x SQL 2 core pack licensees.

Server + CAL licensing:
-I will need 1 x SQL Standard server license
-I will need 100 x SQL device CALs or can I go with 1 x SQL user CAL if all the ATMs are the same user?
I had this question after viewing Way to restrict RDP access in 2008 server by computer name and/or mac address?.

Is SecureTS ever released?
Or is there similar tool?

I keep seeing this error message on two 100% identical (same hardware ProLiant DL380p G8, 8 GB RAM on each, same 2012 R2 o/s, same updates) servers that are currently
doing nothing and have nothing else installed in terms of roles and
features except file server. No Exchange, no DC, etc.
Both are physical servers (NO virtualization running on them) on the same network in the same AD domain as all other servers that do not show this error
They both have Shadow Copies enabled and configured for previous versions of files/folders,

What is the biggest problem in managing an exchange environment today? It is the lack of backups, disaster recovery (DR) plan, testing of the DR plan or believing that it won’t happen to us.
I have just had a Malware Bytes Enterprise Anti Malware database update (v2018.01.27.03) (dated 2018/01/27 15:38:31 GMT) and this has updated on my servers and effectively flagged every server service.

I have managed to get in via vSphere into my DCs and turn off "Website Blocking" which now makes internal DNS work. However I have an Exchange server which wont work and appears to be flagging some of the services for quarantine. Further more restarting the servers causes the "Website Blocking" to enable itself again and the issue persists.

I am on the verge of uninstalling the client on the servers to try and get a stable environement. As I cannot access my email I cannot access my MBAM support so I am unable to raise a case. Does anyone have MBAM and having the same issue and can raise a case?


I am curious if it is a security risk to keep internal files within the same level of the accessible directory. I am using Plesk to manage my server.

Plesk sets up the directory structure as such
  1. vhost
      1. error_docs
      2. http
      3. logs

Within the directory, the http directory is accessible to the public via

i have added additional directories within the directory to keep everything in the same spot. The additional folders contain sensitive information.

I know that these folders are not directly accessible to standard users but im curious if i should move them up the directory hierarchy so i only have the public http directory.  Or is this something i dont have to even worry about

Hi we are using VMware- Virtual appliance for our network infrastructure .I was working on the server room tidying the cables  and I have received an email triggered from VMware infrastructure as follows:

Target: ESX-001.domain.local
Stateless event alarm
Alarm Definition:

Event details:
Uplink redundancy degraded on virtual switch "vSwitch1". Physical NIC vmnic3 is down. Affected portgroups:"NFS".

At the moment the servers are up and running without any problems.
Please let me know if there is a problem , if so where I need to look at to rectify the problem.

Thanks  and  help will be great.
This is a fresh install of Exchange 2016 CU8 on windows server 2016 standard.

Driver letters:


D: Exchange 2016 CU8 ISO (mounted)

After Exchange 2016 CU8 install, the ISO was dismounted and I setup a new data drive for Exchange. The data drive took drive letter D: by default. When I restarted the server, D:\AdvancedDataGovernanceLogs folder was created.

If I change the data drive letter from D: to something else like E: drive, D:\AdvancedDataGovernanceLogs folder does not get created when the server is restarted.

What is AdvancedDataGovernanceLogs folder and how do you change the location?
