SharePoint Admin Tool Belt Addition – C2WTS Troubleshooting

I was troubleshooting an issue with the Claims to Windows Token Service the other day and found a great tool to assist. I was working in a SSRS integrated environment configured with Kerberos and was getting the error “Cannot convert claims to windows token” when configuring a data source to test against. The issue was that the C2WTS service account was not in the local admin group. I had requested this access, but in this environment the local admins were all in an Active Directory Group and I did not have permissions to confirm this and adding the account in local admin explicitly was whipped out with Group Policy. Anyways, enough about the issue..the awesome tool is at and is called c2WTS tester

Add it to your SP Admin tool belt!


SharePoint Invalid File Name Workaround..ish

I’m sure anyne dealing with SharePoint end user support has ran into this error: “The file name you specified is not valid or too long. Specify a different file name.”

Invalid Filename

After some searching we noticed that this is a limitation with all versions of SharePoint! Usually renaming one or two files isn’t too big of a problem (And it never seems to be a problem if they want to get around blocked file types!), but this specific case we needed to upload thousands of documents into SharePoint. I did some more searching around online and found a few different options: powershell (love it, but to train someone who has never used it would be a fun day), create an event receiver to change the file name at the time of upload¬†(not enough time in this case), or find an application capable of renaming bulk files. I found this little gem on sourcefourge:

SharePoint File Fix is capable of renaming bulk files (and even does recursive renames) to make them compatbile with SharePoint. It is a lightweight html application that doesn’t require an install and is very easy to train a user how to use it.
