Since migrating our citrix server farm to a VMware ESX environment client drive mappings have stopped working.

We are running two citrix servers on 4.5 and our VMware environment is runing on ESX 4.1.

It can't be an issue with routing as this issue has only occured since we virtualised our Citrix Server Farm.

Also - client drives for CD/DVD drives and other system partitions on local PC's do appear but some don't.

Client drives only appear if they are given permission by the user.
We run citrix in esxi and our drive mappings are done in a vbscipt in the startup folder and they work fine.

Hi,

We have a similar problem. We use the same system (PS4.5, ESXi 4.1). On the first six VM based citrix server, the client drive (not network drive) mapping is working fine. Now we setup ten more Citrix Servers, and the client drive mapping is not working on these machines.

Same user, same Thin Client:
Connecting to Server X --> USB Drive available
Connecting to Server Y --> USB Drive not available

We went through all our documentations and installation notes, but no hint what we have done to enable.

Any Ideas?

Hi there,

solved it! :-)

I went through some citrix KB articles and compared registry dumps from a working and not working server. Check your registry @
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\NetworkProvider]

On a NOT working server at least CdmService and Webclient were missing. Below is the set of registry keys that worked for our Citrix Servers.
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\NetworkProvider\HwOrder]
"ProviderOrder"="PDVFSNP,CdmService,RDPNP,LanmanWorkstation,WebClient,PnSson"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\NetworkProvider\Order]
"ProviderOrder"="PDVFSNP,CdmService,RDPNP,LanmanWorkstation,WebClient,PnSson"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\NetworkProvider\ShortName]
"CLIENT"="Citrix Clientnetzwerk"

Open in new window


Best Regards, Brummelbart

Thanks for your responses. We resolved this issue a while ago - turn out it was related to a corrupt group policy which was applying to the citrix servers.
