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.

I am trying to create a virtual domain in wampserver, when i try to create one in the "Add a virtualHost" panel i get the message "c:/users/edkna/desktop/allsites/site1 does not exist or is not a directory", even though there is a directory there.
I tried creating a directory in multiple places on my computer (which i have full admin rights to) I am carefull to correctly copy and past the path to the directory and paste it into the "complete absolute path of the virtualhost" field but I get this error message every time. (see the attached screen capture errorMessage.JPG)

Also another issue that is probably related to the above issue, when I tried to add a second directory in  C:\wamp\www  for a another Wordpress site, I get the following error messages:
( ! ) Warning: Unknown: failed to open stream: No such file or directory in Unknown on line 0
( ! ) Fatal error: Unknown: Failed opening required 'C:/wamp/www/site2/index.php' (include_path='.;C:\php\pear') in Unknown on line 0 (see the attached screen capture anothrErrorMessage.JPG)

Can you tell me how to fix this problem?

Hi Dave,
 you said it could be a permissions issue.  Properties/Security show I have full control.  This is also my personal computer which I have all privileges to. are you referring to some other permissions that I am not thinking of? I was able to create virtual domains six months ago, so I don't know of any thing that is different on my computer now.

Hi noci,
 I pasted in the path with …

On Ubuntu 16.04 LTS I need to be able to monitor the entire filesystem for any changes. Can anyone recommend the best free / open source software to use ?

What I want is some software that I fire up, do a scan, leave running in the background, it records any files created or deleted and then presents me with a list or ideally a report of the changes,

Please can someone recommend a program they have personal experience of ?
Hello I was working good and suddenly my windows server stopped sending emails via cdosys.asp and I found was list in CBL. They say: This IP address was detected and listed 85 times in the past 28 days, and 14 times in the past 24 hours. The most recent detection was at Thu Apr 5 15:05:00 2018 UTC +/- 5 minutes

The listing of this IP is because it HELOs as a bare IP address (A bare ip address looks like: ""). It is not HELO'ing as itself ("").

I have windows 2008 and almost we don’t send email just the normal reports of a LMS.

How can I fix the problem I just use my regular IP like years but suddenly stopped working.

Thank you
For my Python RTS / MOBA server,

I am at a decision where I should either make a class for reading UDP activity updates from the clients over TCP activity ( a failsafe)
Should I have a UDPlistener class and a TCPlistener class?
or should I have a packetListener class with a UDPlisten method and  also, a TCPlisten method? - that are each made into Threads?
I think an all-in-one approach would make linking into the game smoother?

both would work, but which would look best? Is Python better suited to one?

I need to setup a new server for a veterinary hospital wth 10 users on Windows 10 workstations. They currently use a workgroup with a workstation running server 2018 for shared data and printers. I want to setup an AD domain because managing user permissions and workstation setup and configuration is getting too time consuming in the workgroup environment. Their database size and shared file storage needs are very low so we don't need enterprise level power. I just want the minimal server hardware and os necessary for AD management, some remote access, group policy changes and to standardize workstation UI and software configuration, plus physical space for server hardware is very limited. Extra capacity for future growth is not necessary because they are at the maximum physical size that is possible for their location.

Thank you
my pc suddenly goes blank screen. What should i do except restarting it?
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.

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

Would really appreciate what else I should be looking at as this has me stumped. Are there any ports on the firewall that need to explicitly be open?

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.

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:

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 …
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?

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?
