Microsoft Site Server (any version) -

SharePoint Portal Server and Exchange 2000 Server It is not recommended ”nor will Microsoft support it ”if you install SharePoint Portal Server and Exchange 2000 on the same computer. It can and probably will create certain known issues. However, we realize that your specific business requirements may justify the need to install SharePoint Portal Server and Exchange 2000 on the same server. To enable both applications on the same server, perform the following tasks : TIP You must install Exchange before SharePoint Portal Server. The Windows 2000 and Exchange 2000 SP1 patches must be applied.
During installation, the Microsoft Search (MSSearch) service is upgraded and the (MSExchangeIS) service is stopped for a short period of time. The full-text index format of all existing indexes on that computer is upgraded the next time the MSSearch starts. NOTE Upgrading the full-text index format can take several hours, depending on the number and size of the existing indexes. There must be enough disk space on the computer to accommodate 120% of the size of the largest full-text index on the drive.
SharePoint Portal Server upgrades MSSearch and full-text indexes; you should not install SharePoint Portal Server on a server that participates in an Exchange Server clustering environment or add a computer running SharePoint Portal Server to a clustered environment. SharePoint Portal Server will not install if four storage groups already exist on the Exchange server. Since some services are shared between SharePoint Portal Server and Exchange2000, removing either one can be trouble for the other: It will cease to operate properly. If this occurs, you must manually restart the following services: -
IIS Admin Service -
SharePoint Portal Server -
Exchange Information Store -
SMTP -
World Wide Web Publishing Service -
Network News Transport Protocol (NNTP) -
Exchange MTA Stacks -
Exchange POP3 -
Exchange IMAP4 -
Exchange Routing Engine You can also create a standard batch file to automatically start these services. NOTE If you remove SharePoint Portal Server from an Exchange 2000 server, Exchange will continue to work.
SharePoint Portal Server and Microsoft SQL Server SharePoint Portal Server will upgrade the existing MSSearch and the full-text index format of all the existing indexes on a computer running Microsoft SQL Server 7.0 or Microsoft SQL Server 2000. The next time MSSearch starts, there must be enough disk space on the computer to accommodate 120% of the size of the largest full-text index on the drive or the upgrade will fail. NOTE Upgrading the full-text index format can take several hours, depending on the number and size of the existing indexes. A message will inform you that the service will be upgraded.
CAUTION Because SharePoint Portal Server upgrades MSSearch and full-text indexes, do not install SharePoint Portal Server on a server that participates in a SQL Server clustering environment or add a computer running SharePoint Portal Server to a clustered environment.
You can install SQL Server on a computer already running SharePoint Portal Server. In this instance, SQL Server uses MSSearch installed by SharePoint Portal Server. If you remove SharePoint Portal Server from a computer that has SQL Server installed, SharePoint Portal Server will not remove the upgraded MSSearch because it is a shared service with SQL Server. Installing SharePoint Portal Server on a Domain Controller If you install SharePoint Portal Server on a domain controller: -
There is not a local Administrators group . If a Coordinator makes an error, there is no possibility for a local administrator to resolve security issues. Only users assigned to the Coordinator role can specify security on folders. -
You may need to restart the DC after installing SharePoint Portal Server. Renaming a SharePoint Portal Server Computer You can rename a SharePoint Portal Server computer at any time. After renaming the server, you must restart it.  |
