By default, the cache size on 5120 MB. If there is more data are needed because the total size of the MSI files is more than the default cache value, then you can adjust the size during the Task Sequence. The size of the Cache is to match by first making an application or Package in SCCM. With SCCM 2007 you could in the Task Sequence by setting the command of the Client installation.
However, this doesn’t work more with SCCM 2012.
To the Cache as an example we use the cache size 99999
Set oShell = WScript.CreateObject (“WScript.shell”)
Set client = CreateObject(“UIResource.UIResourceMgr”)
Set CacheInfo = client.GetCacheInfo CacheInfo.TotalSize = 99999
