I’m stumped and hoping you guys can help get me going in the right direction.

I have 3 client access servers (Exchange 2010) with RPC, OWA, IMAP and SMTP services load balanced behind a Citrix NetScaler.  

What I’m trying to create is a secondary vServer on the NetScaler I can use for post-patch testing of the SMTP service.  The idea being that I could move one of my CA servers out of production and into the test vServer for patch validation then move the server back into production when testing is complete.

Each of my CA servers have 2 NICS: 1 LAN connection (with gateway and DNS) and 1 MS Loopback NIC configured with the IP of our SMTP Receive connector.  The SMTP receive connector is receiving traffic from the Loopback NIC on port 25.
 
What I’ve done to date is create a Host A record for my “smtptest” IP address in DNS.  Then I added another MS Loopback NIC to one of my servers configured with the smtptest IP address.  A receive connector was added to the Hub Transport and configured to receive on port 25 from the smtptest IP address.  I used the same authentication and security settings on the new connector as the existing receive connector.  Then I created a new vServer on the NetScaler, again, using the same configuration on the new vServer as the existing one.

The end result is that I can PING “smtptest” by DNS name and receive a response but cannot telnet to smtptest on port 25.  SMTPtest mail delivery fails as well.  The log from my SMTP Diag Tool …

Hi,

When we are trying to connect to citrix we are getting

This site can’t be reached
citrix.ephs.ealing.sch.uk refused to connect.
Try:

Checking the connection
Checking the proxy and the firewall
ERR_CONNECTION_REFUSED

It was working and since this weekend it is not working at all. How do I trace back where the problem is and where do i start?

Thanks
Arpit

I am new to this and I cannot figure out the life for me why this virtual is coming up as unregistered. I followed our KB - reinstalled VDA 7.6 rebooted and still nothing. Any experts in this area?

Are there major features missing for load balancing purposes? Throughput limits? High cost?

Running ldp.exe on domain controller using domain admin credentials and simple bind, I got the same error the first run. Now it gives me The token supplied to the function is invalid.

Running ldp.exe on a different domain controller on different domain/forest, the results are valid.

So something wrong on first domain controller. How/Where to find the problem?

Thanks!

Hello,

We are are looking into replacing our ADFS Proxy Servers with Citrix Netscaler (See link -> https://www.citrix.com/content/dam/citrix/en_us/documents/products-solutions/guide-to-deploying-netscaler-as-an-active-directory-federation-services-proxy.pdf)

We are also looking at buying Duo and using it for ADFS (Link->https://duo.com/docs/adfs-30)

We don't to make our network engineer go through all of the work switching ADFS proxy over to the Netscaler if will not work with Duo. Wanted to check to see if anyone here has or is doing this?

Thanks!!!

I have a load balancer with a public VIP. The partner can only get the site if they ignore that they perceive the site as unsafe.
I’m fairly the certain my very is valid because other VIPs use it. What are some reasons a client might not trust the cert? Brain storming question.

How do I get user report logs from XenDesktop 7.x? There doesn't appear to be a reporting tools in Studio or Director. Would this be available from the Netscaler? Please advise. Thanks

We have purchased a company (Microsoft Exchange 2010) and will be migrating them to our Microsoft Exchange 2013 environment. In that process, we will need to migrate their SMTP sending devices to our exchange environment. This process is:

- entering the devices' IP into our Exchange 2013 reinjection list
- updating that device with the new SMTP server address of our exchange server

Issue: previous exchange environment operated with an injection list of all IPs: 0.0.0.0-255.255.255.0 so they did not maintain a list. They also operate with a Citrix Netscaler load balancing device which is what they advertise to their devices as the SMTP address.

Question is: how can we effectively find the devices in this Exchange 2010 environment that are using the exchange server to send email with. For example, scan to email printer.

Suggestions please?

Hello,

I have a OID as below
30.118.115.58.115.105.110.103.108.101.58.116.101.115.116.45.109.97.99.104.105.110.101.58.104.116.116.112.64.56.48

Open in new window


I would like to know how can I convert it to it's name using python? I do not want to make any network or localhost call.

this OID is mapped to one of the VSERVER's Name in NetScaler.

We have one user that receives:   Error: not a privileged user when she attempts to connect through the web interface to our Netscaler for VPN access to our network.   Assuming this must be something incorrect with her local client software but can't figure out what or why?  We have tried re-installing it.   We have 200+ users using the same web url and method to connect from home and do not receive this error.  Can anyone help with some basic instructions?  We are not sys admins and they have not responded...we just need to get her working.   Thanks for any assistance.

The ultimate Citrix XenDesktop 7.x internals cheat sheet!
What if you have to shut down the entire Citrix infrastructure for hardware maintenance, software upgrades or "the unknown"? I developed this plan for "the unknown" and hope that it helps you as well. This article explains how to properly shut down and start your ENTIRE Citrix environment.

Hi all,

After having a pen test we have report outlining a number of insecure ciphers that have been highlighted with our Netscaler 7500 appliances. I looking in Traffic managment / SSL/Cipher groups I can see there are 104 polices in here.

Are all these polices in use if they are in the list?

Hi all,

We are currently running a pair of Netscaler in HA mode running build 47.14.

Version NS11.1 51.26.nc

Hello,

We are in the implementation phase of the netscaler vpn solution and we have found the session establishes successfully. During the session internal DNS is able to resolve to the internal DNS server however not within the defined scope is unable to resolve. For example  O365 which is an external resource.

We do not  have split tunneling disabled and need this function disabled. We do have internal DNS servers and 8.8.8.8 has ns servers in the netscaler network configuration .

Any ideas are appreciated

Hello All,

I am about to implement Sharefile with Storage Zone Controllers on premises using the Setup Netscaler for Sharefile wizard.
In the first screen of the wizard in the "Load Balancing Virtual server configuration", there is a checkbox asking to configure Storage Zone Connectors for file shares. I am wondering if I will need to check this option since I will not be configuring any client or deploying XenMobile. What I want sharefile for is to be able configure users in the Sharefile control plane (Citrix Portal) and grant them access to upload documents through this portal. Also I will like to be able to share documents via an url sent in an email.
Would I need to check the connectors check box in my scenario?

Hi Experts,

We have 2 sites with Separate SoreFronts configured. They are in separate locations and there is site to site VPN set up between them.
We have NetScaller set up in one of locations which is Gateway for both sites. When people connecting to netscaller and trying to access citrix which is other location than NetScaller, connection is slow but when they are accessing citrix in the same location as NetScaller connection is fine. I'm assuming that slowness is caused by all traffic routed through Netscaller and then Netscaller routing traffic through VPN link between 2 sites. Is it possible then to set up NetScaller so If user is trying to access citrix which is not on site with Netscaller, he will be still authenticated by Netscaller but then all traffic will be redirected directly to that citrix, instead going through Netscaller? Hope it makes sense😊

Kind Regards,
Marcin
