In a certain project, TSM and DSM need to be installed in a same server. TSM has been deployed, check the port when installing DSM, appear error "80 port: has already been occupied". Cannot continue to install.
Right click the "my computer", left click management, open the "computer management". Select the "services and applications", open the "IIS management". Select the "site" and expand. Stop the "default site".
Cancel pre the interrupted installation, rerun DSM installing software. Check the port again, it appears "port 80: not occupied", then can do the next step installing operation.
After Installed the TSM system, server’s port 80 has been occupied by the default website of the server system website.
First of all it is suggested don’t install the TSM and DSM on the same server as far as possible, but if must do, can use this method to solve the problem.
