Hi Russell, Thanks for your response.
I have an attached file in my first post that shows the screenshot of Create a domain from a table=> Step 1: In ArcCatalog, use the Search tool to locate the Table to Domain tool. Step 2: Double click Table to Domain to start the tool. In the dialog box, click the Browse button next to Input Table. Browse through the C:\ESRIPress\GIST3\Data folder for the table Suffix.txt. Click the table, and then click ADD. No matter what I click (double-left-click, double-right-click, single-left-click, or single-right-click) on the Table to Domain (Data Management) and nothing happens!!! Here in this post attachment is the table Suffix.txt from my C:\ESRIPress\GIST3\Data folder for you to look at. One more thing to tell you: my ArcGIS 10 software program is installed in the C:\Drive of my terminal PC that is connected to Microsoft NT 4 LAN System. Can this cause the problem in accessing the Table to Domain tool? Please kindly help and advise in resolving this strange problem.
Thanks,
Scott Chang
