Is there anyway to remove denied permissions from a group for a folder if I dont have access?

Solution 1:

You will need to take ownership of the folder.

Launch a command prompt as administrator, and then run:
takeown /F C:\Path\to\the\folder

This should take ownership of the folder, and allow you to read and change permissions on it. From here, right-click on it in windows explorer, select Properties, select the Security tab, click Advanced, click Change Permissions, and then select the Deny permission and click Remove. Click OK until the windows are closed.
