SYMPTOMS
Windows 95 clients connecting to Microsoft SNA Server may experience
dropped sessions when idle for an extended period.
CAUSE
This problem occurs when power management is enabled through CMOS or
software on Windows 95 computers. This can occur on laptops or desktop
systems with power management enabled.
When the timeout value is reached, the BIOS enables power management on the
system. On some systems running TCP/IP, this causes Windows 95 to send a
DHCP release of its IP address, causing all TCP/IP sessions to lose
connectivity. Emulator sessions that are active will lose all connectivity
to the SNA Server.
RESOLUTION
Disable power management through either CMOS or software.
