SCCM: Distribution Error and the Ampersand

I came across an interesting problem in SCCM today. A branch distribution point ( BDP ) wasn't replicating a package and it turns out it was because one of the files in the package had an ampersand ( & ) in the file name.

I was seeing this in the ContentTransferManager.log on the BDP:

Unable to enumerate files in E:\BDPTmpWrkFldr\PDP2B6A.tmp (0x80070003)

I came across a Microsoft Knowledge Base article KB967648 that matches the error:

Consider the following scenario:

• Distribution points and branch distribution points exist in a Microsoft System Center Configuration Manager 2007 Service Pack 1 (SP1) site.
• A package is saved on distribution points and on branch distribution points.
• A file name in this package contains an ampersand (&).
• A property of this package is changed on the distribution points.In this scenario, branch distribution points cannot update this package, and an error is encountered. Additionally, package distribution fails, and the package folder on branch distribution points cannot be accessed because of security permissions issues.

There is a hotfix available from Microsoft that is linked from the KB article.
