Updating web pages on www.chem.cmu.edu


If you are the designated web admin for your research group, have your advisor email Seth at esmiller@cmu.edu to have you added to the access list for your group’s website.


Web pages on the Chemistry web server www.chem.cmu.edu are updated through Windows File Sharing using strong password encryption (the server enforces NTLMv2).  You will be sent the groups ‘share name’ when your access is granted.  The shares are ‘hidden shares’ that do not normally display on the list of shared folders, so you’ll need to know the exact share name in advance.  Hidden share names all have a dollar sign (‘$’) at the end of the name, like sharename$.


Access is via your ‘Microsoft Password’, sometimes called your 'Andrew Windows' password.  This password is distinct from the 'Andrew' password that’s used for Andrew email.  To set your Microsoft password, visit http://www.cmu.edu/computing/andrew-windows and use the 'Andrew Windows Password Reset' link on the left.  Some details on the distinction between Andrew and Andrew Windows passwords are at the 'chemserv' link at http://support.chem.cmu.edu.


Accessing shares from Windows:


On most PCs you can access the share by going to the Start menu, Run, and typing in




Where ‘sharename’ is the name of your group’s shared folder.  ‘Rembrandt’ is the name of the actual machine that hosts www.chem.cmu.edu.


Log on using the ‘andrew\’ notation for your user name.  For example:


            User name:  andrew\ap2a

            Password: (Andrew Windows password)

            (For security reasons, do not check the ‘Remember my password’ checkbox.)


The ‘andrew\’ notation tells the server that the user name you’re entering is part of the campus-wide Microsoft domain called Andrew, rather than an account created locally on the remote computer.  Microsoft domain accounts, also called Andrew Windows accounts, are separate from the account that you use to read your email.  See the above section for the distinction and setting your initial password.  If your computer is a member of the campus ‘Andrew Windows’ domain, you may not even be asked for a user name or password, as the PC you’re on can pass your existing domain authentication to the server directly.


If you do not see a login window and also get an ‘access denied’ message, it may be the case that your computer automatically connected to the server using a guest or another account, succeeded in getting an initial connection to the server itself with that account, but that account doesn’t have access to the shared folder.  In this case you can manually delete existing network connections and manually specify what user name to connect with by using these steps:


Go to the Start menu, Run, CMD.
In the command window that appears enter these commands:

Net use * /delete

Net use * \\rembrandt.chem.cmu.edu\sharename$ * /user:andrew\userID

            (replacing ‘sharename’ and ‘userID’ with your groups sharename and your user name.)


The first ‘net use * /delete’ command discards any previous network credentials that Windows might be trying to use by default to authenticate to the share which might not have access.  The second command explicitly tells Windows what user name to authenticate with and maps a new drive letter to the share.  When done modifying the site contents, use the 'net use * /delete' command to delete the drive letter and remove the credentials.

Accessing shares from OS X:


If this Mac has never been configured to connect to Chemserv, follow the steps at the ‘chemserv’ link at http://support.chem.cmu.edu to install the ‘Microsoft UAM’ software first.


Select the Go menu, Connect to Server, and enter




Where ‘sharename’ is the name of your group’s shared folder.  The ‘Workgroup or Domain’ field will automatically be set to the ‘ANDREW’ domain, which is correct.  In the Name field use your userID without the ‘andrew\’ notation.  For example, just ‘ap2a’.  For the Password field enter your Microsoft password.  For information on your Microsoft password, see the first section of this page.


Please note that www.chem.cmu.edu does not support ‘Resource forks’, meaning that all of your files will have to have the appropriate filename extension such as .html.  Also, filenames must be valid Windows filenames, meaning they can not contain the following characters: \ / : * ? “ < > |


When done updating your pages, be sure to ‘dismount’ the shared volume by clicking the eject icon next to the volume name in the Finder.
