Symptoms or Error No errors are seen by the user or shown in event logs on the server. The logon script is delayed by up to 5 minutes which has been observed from Windows 8.1 or Windows 2012 machines users. If you manually execute the user script from within the users session it works fine. The same issue can be seen in a Microsoft’s Remote Desktop (RDP) session.
Environment XenApp 6.
XenDesktop7 is a unified environment, where Applications & Desktops are delivered from the same platform.
This is the latest product in the XenApp & XenDesktop family, which combines both the famous previous products of Citrix, XenApp (Application Virtualization) & XenDesktop (Desktop Virtualization).
Before going through the below things, would advise to clearly understand XenDesktop architecture first, so that it will be easier to understand how the merger happened.
Key Differences Between XenApp And XenDesktop7
Many administrators simply download and install Adobe Reader on their XenApp servers. However, many small tweaks, which could improve end user experience and/or prevent users from corrupting Adobe Reader for other users on a server, should be considered as part of XenApp deployments. This blog outlines configurations to modify a typical user’s experience while working in Adobe Reader.
Note: Although the information below focuses on Adobe Reader 11 settings, most of the optimizations can be applied to other versions of Adobe Reader by modifying the version in the path of the directory or registry setting.
When you are using xendesktop 7.x or XenApp 7.x, you might see an error while configuring your database which says, “The current credentials have insufficient privileges to access the database server and perform the necessary operations. Do you wish to enter alternative credentials?”.
Solution1: If your firewall is turned on, create an inbound rule to allow 1433 port. In most of the cases this works.
Solution2: If it still doesnt work, follow the article, http://support.
Citrix XenDesktop login process and ports used
The user submits the credentials to the Citrix Web Interface site (http/https – port 80/443).
Web Interface passes the user credentials to the Desktop Delivery Controller with XML service (port 80/443).
DDC verifies the user authorization with Microsoft Active Directory (LDAP and GC – port 389/636 and 3268/3269).
DDC queries the database for the user’s desktop groups and user’s profile information (ports 1433/1434). Now user sees the desktop groups, he has access to.
Introduction The XenApp move to FlexCast Management Architecture (FMA) brings conceptual and terminology shifts. This blog explains how you can think about XenApp 6 entities in a XenApp 7.5 world.
For simplicity, “XenApp 7” here is meant to include any current point release such as XenApp 7.5, and “XenApp 6” is meant to include any current point release such as XenApp 6.5.
Although not exact equivalents, the following table helps map XenApp 6 functional elements to XenApp 7:
A very popular customization of Web Interface is to hide certain resources (applications, desktops or documents) from users. StoreFront 2.5 provides a resource filter to support this out of the box. Resources can be filtered by type or keyword. The filter you set up for a Store will work for both the Receiver for Web and native receivers (e.g. Receiver for Windows). This short article shows you how to configure StoreFront resource filter to hide certain resources by type or keyword.
Netscaler is available in either a hardware or software based appliance.
Hardware options, MPX and SDX include single and multi-tenant devices, in addition to FIPS compliant and high SSL throughput appliances. Software-based options, VPX and CPX include virtual hypervisor-based and containerized microservice offerings. MPX: Available in burst packs and pay-as-you go grow options. Supports more than 4.5 gbps of ssl throughput. It is federal information processing standard compliant. Hardware-based application delivery appliances with a performance upto 500 Mbps–200 Gbps.
Understanding NetScaler IP Addresses Basic Networking:
Netscaler owned IP addresses:
Netscaler IP (NSIP), MIP (Mapped IP), SNIP (Subnet IP), VIP (Virtual IP), GSLB site IP, Cluster IP.
NetScaler IP (NSIP) address:
The NSIP address (NetScaler IP Address) is the IP address which is used by the Administrator to manage and configure the NetScaler. It is mandatory when setting up and configuring the NetScaler for the first time, there can only be one NSIP address, it can not be removed and when it’s changed you will have to reboot the NetScaler.
On older Netscaler appliances, the command to clear your Netscaler configuration and reset it to factory defaults used to be:
clear config –c y
But on newer devices, the command is:
clear ns config level
where level is one of the following:
1. basic – which clears everything except NSIP, MIPs, SNIPs, network settings, HA, features, and the nsroot account
2. extended – which clears everything except NSIP, MIPs, SNIPs, network settings, & HA
