Hi, I have a requirement to allow user's to logon to a published desktop on a known machine i.e. a company laptop with known MAC address. Which I want to allow the user's to see the local client drive mappings. But... If that user's logs onto an unknown machine I do not want to have the local drives mapped. Running XenApp 5.0 on 2003 R2 server with AAC on 4.6. thanks Ronnie Visit our website : www.ltai.ie __________________________________________ Lufthansa Technik Airmotive Ireland Limited.
