LogMask REG_DWORD 0 - 0xffffffff
Specifies a bit mask for logging debug information. After changing this value,
stop and start the ICA Browser to start logging to the file
%systemRoot%\Ibrowser.log. The bit mask values are:
Bit Mask
0x00000001
0x00000002
0x00000004
0x00000008
0x00000010
0x00000020
0x00000040
0x00000080
0x00000100
0x00000200
0x10000000
0x20000000
LogToDebugger REG_DWORD 0 - 1
Specifies that logging messages should be written to the kernel debugger in
addition to the log file.
MasterDeclareTime REG_DWORD 0 - 0xffffffff seconds (3600 = default)
Indicates how frequently the master browser broadcasts a master declare. A
master declare is used to detect multiple master browsers on the same network.
If a master browser ever receives this packet from another browser, it forces an
election to get rid of the extra master browser. This value can be set to zero to
disable master browser declares.
NotMasterBrowser REG_DWORD 0 or 1
When this value is set to 1, it lowers the browser's priority during a master
browser election. This prevents this browser from becoming the master
browser.
PingAddressTime REG_DWORD
Specifies the time a browser waits, after sending a ping request, for a ping
reply. If no ping reply is received, the browser tries to send the update again.
The browser uses pings to verify a server still exists before returning the
address of a server to the client.
