Exchange Server 4.0

III-121 If you have tried to change your Exchange password, chances are you have encountered this error: “The NT Domain password could not be changed. A required action was not successful due to an unspecified error.” You need to add the following registry parameters to fix this problem.

Hive: HKEY_LOCAL_MACHINE
Key: CurrentControlSet\Control\LSA

Add the following value under the LSA key:

Value Name: NetWareClientSupport
Data Type: REG_DWORD
Value: 1

Use this entry if you are running NWLINK.

III-122 Hive: HKEY_LOCAL_MACHINE
Key: CurrentControlSet\Control\LSA

Add the following value under the LSA key:

Value Name: TcpipClientSupport
Data Type: REG_DWORD
Value: 1

Use this entry if you are running TCP/IP. Restart the machine for these changes to take effect.

III-123 If you cannot communicate with your Exchange Server using your Exchange client and have recently installed a firewall, you may need to change the following registry entries.

Hive: HKEY_LOCAL_MACHINE
Key: System\CurrentControlSet\Services\MSExchangeIS\ ParametersSystem
Value Name: TCP/IP Port
Data Type: REG_DWORD
Value: < valid TCP/IP Port number >

III-124 Hive: HKEY_LOCAL_MACHINE
Key: System\CurrentControlSet\Services\MSExchangeIS\ Parameters
Value Name: TCP/IP Port
Data Type: REG_DWORD
Value: < valid TCP/IP Port number >

Some Internet firewall software doesn’t accept the TCP/IP ports Exchange uses to communicate via RPC. You need to modify these ports on the Exchange server to something that your firewall software can use. Restart Exchange for these changes to take effect.

III-125 The Exchange client installs multiple protocols so that it can connect to the server using any one. As a result, sometimes it seems that Exchange takes forever to load. You can speed things up by eliminating the protocols you don’t use. For example, if you use only TCP/IP, you can change the following registry entry.

Hive: HKEY_LOCAL_MACHINE
Key: System\CurrentControlSet\ServicesMSExchangeMTA\ Parameters\MT
Value Name: gateway clients
Data Type: REG_DWORD
Value: 0x20

The default setting is 0x8 and is fine under normal conditions. If your installation has several gateways or connections configured, try increasing this parameter.

Internet News and Mail

III-126 If you need to move the address book file, you need to modify these two registry values. This change is especially useful if you have just upgraded your hard drive and want to move some of the larger files to a disk with more room.

Hive: HKEY_CURRENT_USER
Key: Software\Microsoft\Internet Mail and News
Value Name: Store Root
Data Type: REG_SZ
Value: < fully qualified path and directory >

This value sets where Internet Explorer stores the address book files. Be sure to include the drive and fully qualified path.

III-127 Hive: HKEY_CURRENT_USER
Key: Software\Microsoft\WAB\
Value Name: Wab File Name
Data Type: REG_SZ
Value: < fully qualified path and directory >

This value is the actual location of the .wab files, in the format username.wab. If your login is tim, your wab file is tim.wab.
