Remove a WiFi Profile in Windows 8

by ⋅ 2 Comments

This morning I was confronted with an email from the service desk because the Wi-Fi BYOD network authentication had been changed. All existing accounts were removed and BYOD users had to apply for a new user account.  I created a new user account and tried connecting to the existing WiFi BYOD network. Windows 8 detected my old username/password were not valided and requested the new password. Unfortunattely not only my password, but also my username had been changed.

BYOD

For some reason it’s not possible to delete the username of WiFI Profile from within the GUI in Windows 8 anymore. Luckily  there are several other alternatives to delete or manage an existing WiFi profile. Read More →

Citrix PVS 6.1 IPC Error (Multihomed)

by ⋅ 3 Comments

In the process of upgrading an old Citrix PVS 5.6 Farm I did a fresh installation of Citrix Provisioning Server 6.1 ( CPVS61016v2) on Windows 2008 R2.  First I wanted to add some existing vDisks, which were located on the local PVS store. Unfortunately I was unable to add an existing vDisks, according to the PVS Console no new disk where found.

After I had checked that the vDisk files (.vdk/.pvp) were actually present I decided to validate the path for my store.

The validation tool stated a IPC error. The Citrix KB contains an article which sounded familiar “CTX134158 IPC Error when Validating Paths for Store on Provisioning Services Server”. This problem would have been solved with update CPVS61E003, the only problem was I’m running update CPVS61016v2

Install Citrix XenClient 2.1 with a USB Key

by ⋅ Leave a Comment

Today I finally received a new laptop (HP Elitebook 8760W) which is on the Citrix XenClient HCL. Due to a ‘small’ primary SSD disk (160GB) I exchanged the cd-rom device for a additional harddisk, to store additional virtual machines. Without the cd-rom drive I had to install Citrix XenClient 2.1 with a bootable USB Key. Creating a bootable USB Key was pretty straight forward:

  • Download Universal USB Installer
  • Download Citrix XenClient 2.1 ISO
  • Start Universal USB Installer
    • Step 1: Try Unlisted Linux ISO (New Syslinux)
    • Step 2: Select the XenClient ISO
    • Step 3: Select your USB Key
    • Step 4: Select Format Drive
    • Step 5: Hit Create !

Process name (>15 characters) issue after upgrading RES WM 2011 SR3

by ⋅ 1 Comment

After analyzing the release notes of RES WM 2011 SR2/SR3, we decided to upgrade our customer site from RES WM SR1. As usual the upgrade went very smooth and seemed like a walk in the park.

A couple of days after the upgrade to SR3 we suddenly received a lot of support calls regarding blocked applications. We noticed that the AppGuard log was full of processes being blocked. This was quite strange because no new applications were deployed in the last couple of weeks.

Prior to SR2 the authorized process name field could only contain 15 characters. A long filename like “LongProcessName.exe” was registered as “LongProcessName”. No options were available to change this.

RES Workspace Manager Printers.lst

by ⋅ Leave a Comment

Met RES WM is het mogelijk om netwerk printers te koppelen binnen de gebruikerssessie. Op deze manier kan een beheerder vooraf precies instellen welke printers een gebruiker toegewezen krijgt binnen zijn of haar sessie, afhankelijk van authorisatie of groepslidmaatschap.

Het toewijzen van een printer kan op verschillende manieren worden gedaan, bijvoorbeeld aan de hand van een AD Groepslidmaatschap, Powerzone, Clientnaam of Workspace.Wij maken in veel gevallen gebruik van een AD Groepslidmaatschap, zodat het toekennen van printers door authoristiebeheer in de AD kan worden uitgevoerd en hiervoor geen mutaties in de RES WM configuratie behoeven te worden gemaakt.

Buiten deze statische printers (toegekend op basis van een groepslidmaatschap) is het voor zwervende gebruikers ook handig als men in ieder geval één printer krijgt op de locatie waar men op dat moment werkzaam is. Hiervoor maken we gebruik van Powerzones, waarbij we bijvoorbeeld een client VLAN kunnen gebruiken voor het koppelen van printers.
