Exceptions, if any, are noted in this section. If an update version, service pack or Knowledge Base (KB) number appears with a product name, the behavior changed in that update. The new behavior also applies to subsequent updates unless otherwise specified. If a product edition appears with the product version, behavior is different in that product edition.

Unless otherwise specified, any statement of optional behavior in this specification that is prescribed using the terms "SHOULD" or "SHOULD NOT" implies product behavior in accordance with the SHOULD or SHOULD NOT prescription. Unless otherwise specified, the term "MAY" implies that the product does not follow the prescription.

<1> Section 1.6: This protocol is not supported in Windows NT operating system.

<2> Section 2.1.2.1: Mutual authentication is used by default on Windows, except on Windows 2000 or Windows XP operating system Service Pack 1 (SP1), in which No Authentication is used.

<3> Section 2.1.2.2: In applicable Windows releases, the data that is necessary to construct the name object for the Transaction Internet Protocol (TIP) interoperability provider implementation is found in the Windows registry.

<4> Section 2.2.5.1.3.4: In Windows, except Windows NT and Windows 2000, a GUID is used for the szTxId field in the OLETX_TIP_TX_ID structure. If szTxId is set to 0x0000000000000000 (GUID null) and the fAsync flag is set to 0x00000001 in the pull request, a new GUID will be generated and returned in the guidTx field for the TXUSER_TIPPROXYGATEWAY_MTAG_PULLED message.

<5> Section 3.3.5.1.1: In Windows-based clients, except Windows NT, Windows 2000, Windows XP, and Windows Vista, if the Allow TIP flag of the Core Transaction Manager Facet ([MS-DTCO] section 3.2.1) is set to FALSE, the TIP interoperability provider will not be established as a protocol extension, and no RPC endpoint will be established to receive the message. Therefore, any incoming message will be rejected with an RPC error.

<6> Section 3.3.5.1.1: In Windows, except Windows NT and Windows 2000, a GUID is used for the szTxId field in the OLETX_TIP_TX_ID structure. If szTxId is set to 0x0000000000000000 (GUID NULL) and the fAsync flag is set to 0x00000001 in the pull request, a new GUID will be generated and returned in the guidTx field for the TXUSER_TIPPROXYGATEWAY_MTAG_PULLED message.

<7> Section 3.3.5.1.2: In Windows-based clients, except Windows NT, Windows 2000, Windows XP, and Windows Vista, if the Allow TIP flag of the Core Transaction Manager Facet ([MS-DTCO] section 3.2.1) is set to FALSE, the TIP interoperability provider will not be established as a protocol extension, and no RPC endpoint will be established to receive the message. Therefore, any incoming message will be rejected with an RPC error.

<8> Section 3.3.7.1.1: In Windows, the log size is configurable and stored in the registry. The default log size value is 4 MB and the default maximum size is 512 MB.

<9> Section 3.3.7.1.2: In Windows, the log size is configurable and stored in the registry. The default log size value is 4 MB and the default maximum size is 512 MB.

<10> Section 3.3.7.2.1: In Windows, the log size is configurable and stored in the registry. The default log size value is 4 MB and the default maximum size is 512 MB.

<11> Section 3.3.7.2.3: In Windows, the log size is configurable and stored in the registry. The default log size value is 4 MB and the default maximum size is 512 MB.

<12> Section 5: In Windows, except Windows NT and Windows 2000, the implementation of this protocol supports both the mutual authentication and incoming authentication transport security settings.
