I get the error below when trying to update the package on the DPs. The servers have enough disk space, there are no users trying to get to that dir (xxx0015c), and the name is under 128 chars. I have beaten my head against a wall for too long trying to figure this issue out. This happens with another package that i have too, so this isn't the only one.
SMS Distribution Manager failed to copy package "xxx0015C" from "D:\Shared\source\SAPOfficePlugin\" to "MSWNET:["SMS_SITE=xxx"]\\xxxFS\SMSPKGD$\xxx0015C\".
Possible cause: SMS Distribution Manager does not have sufficient rights to read from the package source directory or to write to the destination directory on the distribution point.
Solution: In the SMS Administrator console, verify that the site system connection accounts have sufficient privileges to the source and destination directories.
Possible cause: The distribution point might not be accessible to SMS Distribution Manager running on the site server.
Solution: If users are currently accessing the package files on the distribution point, disconnect the users first. If the package distribution point is located on a Windows NT computer, you can force users to disconnect by clicking on the "Disconnect users from distribution points" box in the Data Access tab of the Package Properties dialog box.
Possible cause: The distribution point does not have enough free disk space to store the package.
Solution: Verify that there is enough free disk space.
Possible cause: The package source directory contains files with long file names and the total length of the path exceeds the maximum length supported by the operating system.
Solution: Reduce the number of folders defined for the package, shorten the filename, or consider bundling the files using a compression utility.
