The system cannot find the path specified.
This issue occurs if an application pool that is associated with the Windows SharePoint Services 2.0 Administration Web site includes non-alphanumeric characters in the name. For example, this issue occurs if an application pool has the following name
In this case, the Windows SharePoint Services 2.0 Internet Information Services (IIS) Wrapper cannot correctly interpret the name of the application pool during the upgrade process.

Click Start, point to Administrative Tools, and then click Internet Information Services (IIS) Manager.
Expand ServerName (local computer), and then click Application Pools.
On the Action menu, right-click the Windows SharePoint Services 2.0 application pool that contains the non-alphanumeric characters, point to All Tasks, and then click Save Configuration to a File.
In the Save Configuration to a File dialog box, type a name for the file, enter the location where you want to save the file, and then click OK.
On the Action menu, right-click Application Pools, point to New, and then click Application Pool (from file).
In the Import Configuration dialog box, click Browse, locate the file that you saved in step 5, click Read File, and then click OK.
In the Application pool ID box, type a name for the application pool by using only alphanumeric characters. For example, type WSSAdministration.
Under ServerName (local computer), expand Web Sites, expand Default Web Site, right-click SharePoint Central Administration, and then click Properties.
