Does anyone have a workaround for this 2008 defect? I have tried all the proposed python and mxddoctor solutions without luck. Inserting entries into the hosts file for old server (actually a server in a different domain) works but is not allowed in the government production environment.
The MXD still contains old arcgis connection information and thus when opening the MXD you suffer a delay of up to 50 seconds.
Map documents (MXDs) preserve the layers' old server information after resetting the data source, which causes slowness in opening the documents if the older server is taken off the network.
