Caution remember to back up your registry before messing with it! This is a user tip. Thethin.net and Worldofasp suggests that this procedure only be used for testing purposes in a test environment. When an ICA client logs onto a Windows 2000 server before it is activated, or if they do not have a Windows NT/2000 machine, they will receive a 90-day temporary license. Once this license runs out they will no longer be able to connect to the Windows 2000 server. Below is a workaround that will work for the 90 days, but then you will have to repeat these steps. Step 1: Apply Microsoft`s fix Q287687 This fix needs to be applied to the Windows 2000 server. For more information you can reference TechNet Article, Q287687 - Terminal Services Licensing Enhancements. Step 2 The next step is to use Regedt32 or Regedit to r emove the following registry entries on the CLIENT`S machine: HKEY_LOCAL_MACHINESOFTWAREMicrosoftMSLicensingStore. Remove both the license000 and license001 keys. Removing these keys will force the Windows 2000 server to re-assign a license for the client`s machine. Step 3 The final step is to rename the icaapi.dll located on the server under winntsystem32 to icaapi.old. Once a client logs onto the server the icaapi.dll will automatically be recreated. --------------------------------- "Grant, Lachlan ISMC:EX" <Lachlan.Grant@xxxxxxxxx> wrote: @page Section1 {size: 8.5in 11.0in; margin: 1.0in 1.25in 1.0in 1.25in; } P.MsoNormal { FONT-SIZE: 12pt; MARGIN: 0in 0in 0pt; FONT-FAMILY: "Times New Roman" } LI.MsoNormal { FONT-SIZE: 12pt; MARGIN: 0in 0in 0pt; FONT-FAMILY: "Times New Roman" } DIV.MsoNormal { FONT-SIZE: 12pt; MARGIN: 0in 0in 0pt; FONT-FAMILY: "Times New Roman" } A:link { COLOR: blue; TEXT-DECORATION: underline } SPAN.MsoHyperlink { COLOR: blue; TEXT-DECORATION: underline } A:visited { COLOR: purple; TEXT-DECORATION: underline } SPAN.MsoHyperlinkFollowed { COLOR: purple; TEXT-DECORATION: underline } SPAN.EmailStyle17 { COLOR: windowtext; FONT-FAMILY: Arial; mso-style-type: personal-compose } DIV.Section1 { page: Section1 } Depends on the type of TS licenses. If you are using Per User TS licensing, then you can wait for them to expire. If you are using Per Device TS licensing, then you will have to call the MS clearinghouse for them to disable all your current licenses and then give you new(replacement) licenses. -----Original Message----- From: windows2000-bounce@xxxxxxxxxxxxx [mailto:windows2000-bounce@xxxxxxxxxxxxx] On Behalf Of Mike Semon Sent: March 7, 2006 1:41 PM To: windows2000@xxxxxxxxxxxxx Subject: [windows2000] Re: terminal service licensing?? No, they expire in 89 days on their own. If you are out of licenses you maybe able to use temporary licenses until they are returned to license pool. -Mike -----Original Message----- From: windows2000-bounce@xxxxxxxxxxxxx [mailto:windows2000-bounce@xxxxxxxxxxxxx]On Behalf Of Jonathan Jesse Sent: Tuesday, March 07, 2006 2:33 PM To: windows2000@xxxxxxxxxxxxx Subject: [windows2000] terminal service licensing??
