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.

How can we use the secondary Citrix NetScaler Server, in an H.A. pair to safely test out new configurations before the same changes are propagated to the other NetScaler?

We have 2 x version 12.0 Citrix NetScaler Servers in our environment.  They both are setup for auto-sync and propagation by default; but according to websites:

- https://support.citrix.com/article/CTX124439 
- https://docs.citrix.com/zh-cn/netscaler/11/system/high-availability-introduction/configuring-command-propagation-high-availability.html

There are commands to that can be executed to turn the HA Sync and HA Propagation off and then back on later.  At my company we would like to test out a 2 factor authentication option (during a planned maintenance window) and see how that works before it is available for all of the users.  I am thinking of doing the following:

1.  Enable the 2 factor authentication settings on the Authentication server.
       a.  Whatever it may be, that is a separate topic from this question.

2.  Then after the Authentication server is ready, disable auto-sync and auto-propagation on the NetScaler HA-Pair.

3.  Then configure the secondary NetScaler to work with the 2nd factor Authentication server.
        a.  Then plan a maintenance window to temporarily make the secondary NetScaler Server into the new primary NetScaler Server.
        b.  When I fail over the primary server, the secondary server will then become the new 'primary' server …

Hi, I have a WD Sentinel dx4000 sunning server 2012R2.  Actually my client does.  Problem is he forgot the password.  I was going to use my password reset CD, but the problem is, there is no display port on this sucker so I can't see whats going on at boot up.  

Question, is there a way to connect a display to this thing?  Or is there another way to reset the password on it?

Thanks a ton.

We have a ML310e Gen 8 that we just re-installed Windows Server 2012 Essentials (not Essentials R2) on and it keeps having an issue with rebooting.

Here's what happens:

You can reboot from the GUI with no issues.

When you reboot from command prompt, it locks up and the processor starts to overheat. You get the red hardware light on the front and you have to power it down manually.

We have updated the BIOS and intelligent provisioning. We did hardware scans and they came back clean. There's a post that says that this version has this same problem when you use a password with special characters in it. We changed the password and we are not using special characters.

Any ideas? This is really weird.

I have purchased Server 2016 and have the key being delivered to me. In the meantime, I would like to go ahead and download the ISO so I can create the VM. I can go to MS site to get the eval version but when trying to download, it will only download the Datacenter edition. Any ideas where I can download Server 2016 Standard 16 core and I will license it when I receive the key?

SIP and Primary SMTP domains do not match. Skype for Business 2015 client displays EWS not deployed.
Hello, I have an Exchange 2007 and Skype for Business 2015 Server on-premise solution deployed.
Originally, functioning fine with SAN certs using <company>.org domain for required certs on mail server and SfB 2015 Standard Edition solution (Standard, Edge and WAP servers).
Primary SMTP domain was <longcompanyname>.com  (domain NOT included in the SAN certs) and everything functioned fine including Conversation History and Calendar synch between Outlook (2007-2013) and Skype for Business 2015 client.
Fast forward a few years and....
New domain purchased and Primary SMTP for each user changed to <shortcompanyname>.com
NOW, Conversation History and Calendar do NOT synch with Outlook anymore.
Research appeared to state I can have this circumstance without issue after running 'Set-CsClientPolicy -DisableEmailComparisonCheck $true'
Ran the powershell command on the SfB Standard Edition server, rebooted test client and SfB solution. STill Outlook Integration Error and EWS not deployed in SfB client Configuration info.
Advice?

Hi

I am looking for advice on the following:

I have an issue within my Citrix VDI environment, that when VDI Desktops not in use are powered off for a pre-longed period of time, they automatically get placed into Maintenance mode. According to a Citrix article there is a DWORD to amend to be able do disable this behviour, which involves changing to a NEGATIVE value. I can't see how this is done as my undserstanding was a DWORD can only accept a 0 upwards:

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

DesktopServer\MaxFailedRegistrationsAllowed

DWORD

2

Controls automatic placement of power-managed VMs into maintenance mode following repeated failures to register with a DDC.

If a VM is started-up by the broker service but fails to register after the period defined by the MaxRegistrationDelayMin setting (default 20 minutes), it is shutdown again.

The MaxFailedRegistrationsAllowed value defines the maximum number of times that this start-up, registration failure, shut down cycle is allowed to repeat before a subsequent registration failure causes the VM to be automatically placed into maintenance mode.

 

The default value of 2 means that if the VM fails to register 3 times in succession, it will be automatically placed into maintenance mode.

Setting MaxFailedRegistrationsAllowed to a negative value (0xFFFFFFFF) disables this behavior and prevents VMs from ever being automatically placed into maintenance mode.

I have been to many KB articles about CA root cert validation period and still have doubt about it and want to clear it. I am about to work on a root CA to increase the validity period as well to increases the issued certificate period.
We have a CA root server and this  server is issuing (no subordinate server in place) the certificate with five years . We now want to renew the CA 's root cert as well as the issued certs period to another 5 years.
My understanding from the EE, nothing I can do with issued certificates and they will expire what ever I do with root server. In this case , I first have to change the validity period in CApolicy.inf file and renew the certificate of CA root server to 10 years, hence this will increase the validation of CA's root certificate as desired (10 years or more).
But the old issued certificates to the clients are chained to old issued template, in this case, the old issued certificates will be expired soon even after changing the value of CAplicy.inf file .
To remediate the issue, the next step is that I have to create new issuing template and issue the certificates to client by GPO.
I have to issue the listed below commands to the server In order for me to set  the  AD's templates period to 5 years as we want otherwise the AD's templates will be staying with old's validation period?
certutil -setreg CA\ValidityPeriodUnits 10
certutil -setreg CA\ValidityPeriod Years
net stop certsvc && net start certsvc

I have Dedicated server on Hetzner. Server is located in Germany.

Server has 256GB RAM 6 CPUs (12 Threads)... In coclusion, it is quite good one. I have CENTOS 7.5. EA4.

Problem is with SSL. Every day for about 2 hours we have 40 requests in one second and at that moment finishing requests takes about 20 seconds sometimes.

While Non SSL takes 0.5 and lower mostly.

There is some exapmle page

http://viber.ge/index.php


After few second you will see responce time and it varies a lot.

From 13:00 to 15:30 (UTC+4) SSL requests take the msot time.

Even if u open this link with SSL and without u might see the difference.

I have WHM available and I've noticed ModSecurity and wonder if it might be the problem.

I have already applied most of the setting provided here but they are not much about SSL.

Could anyone point out where should I look to resolve this issue?

Hi

I support a client who has a 5 Year old Dell PowerEdge R520 Server 2008 r2 on which we've recently been seeing some BSOD's, one this month one last month and the one back in Oct. Dumpcheck says it could be caused by memory corruption but I'm no expert at analysing such files, see below. I know it says a possible problem with the disk subsystem but can anyone suggest a more detailed explanation, i.e. does this look like a hardware issue of some sort?

Thanks

Problems with the Etsy Platform, recently...

I have a friend who was doing well for years on Etsy, selling crafts and keeping busy, with a work backlog that was quite dependable. But then it shut off, like a light-switch.

And others I know who depend on Etsy also seem to have the volume of business shot off.

Is this a known problem?

Was there, perhaps, a software change that caused a problem that can be rectified?

Please give me as much information as you have to help me see if there is anything that can be done.


Thanks!
