Citrix has made two changes to the “free” NetScaler VPX offerings. Specifically, Citrix has : Changed NetScaler VPX Express from 1 Mbps to 5Mbps Added a new “free” offering, VPX Developer Edition, a throughput-limited Platinum version that is available only to NetScaler customers.

Microsoft App-V Team published another quick tip on an issue you might run into where an application virtualized with Microsoft App-V may disappear and no longer become streamable after enabling drive encryption on App-V clients. This is due to the drive encryption locking the associated OSD files. If this happens and if the OSD files are not available after several
Tips and Best Practices Scaling unified communications systems with high performance requires a load balancing solution. Whether you are a new load balancing customer, or have a lot of experience with load balancers, it’s important to always check the basics. In a recent deployment we discovered that even when using access vlans and no tagging, there are still some simple guidelines
Another Citrix article about Load Balancing and Netscaler related to Backup Persistence. The NetScaler Load Balancer uses the backup persistence option when the primary persistence fails. For example, the primary persistence type is set to Cookie Insert, and backup persistence is set to Source IP. When the client browsers do not support cookies, Source IP persistence is used. To set
Citrix has published an interesting article about LDAP integration when used with NetScaler. Here details about this. LDAP stands for Lightweight Directory Access Protocol. As the name suggests, it is a lightweight protocol for accessing directory services, specifically X.500-based directory services. LDAP runs over TCP/IP or other connection oriented transfer services. LDAP is an IETF Standard Track protocol and is specified
Citrix Blog posted another post about Citrix NetScaler. It is already hardended and only VIP’s will respond to TCP handshakes. However here are some more considerations for hardening your deployment. Hardening takes place by implementing the following on the Citrix NetScaler Load Balancer – Securing NetScaler system communication, Access Control Lists (ACL), Securing the NetScaler system using RPCNode and External authentication.
Configuring Persistence Based on Source and Destination IP Addresses The Citrix NetScaler initially selects a server by using a load balancing method. With persistence configured, enabling the NetScaler to send any subsequent client requests to the selected server, the server can access state information for that client. If persistence is configured, it overrides the load balancing methods once the server has been
