Late last week, users reported problems with dial-up after installing the MS06-025 critical patch for Windows' Routing and Remote Access (RRA) service. Microsoft immediately opened a case file for the bug.
Tuesday, the Redmond, Wash. developer posted a new document to its support site that outlined the issue.
"This is an older technology that is rarely used by modern dial-up connections," the Microsoft support note read. "If dial-up scripting is used in a connection, the connection may stop responding. This behavior does not affect any dial-up connections that do not use dial-up scripting."
Microsoft said it was working on a revised update, but that in the meantime companies that needed dial-up scripting should swear off installing MS06-025. As is its practice, Microsoft didn't set a deadline for pushing out a re-patched patch.
This isn't the first time Microsoft has had to fix an update. In April, it re-issued a patch to eliminate a slew of bad behaviors that the original caused on systems running older Hewlett-Packard software or NVIDIA graphics drivers.
June's patch batch included MS06-025 and 11 other bulletins, the majority of which were classified as "critical," Microsoft's most serious threat label.
