Issues that the service pack fixes
- Bulk approval of updates now does not overwrite existing approvals. Instead, bulk approval now updates to a new target group. Bulk approval does not overwrite the existing approvals of the old target groups. By default, bulk approval will add to the existing set of approvals for an update that is not approved.
- Optional approvals are considered when computing
effective approval for overlapping target groups. A required approval will override an optional approval in the following scenario:
Note We recommend that you use the WSUS APIs to "optionally"
approve updates for WSUS 3.0 SP1 and to approve updates that are not critical updates or security
- A computer is a member of multiple target groups.
- An update is approved for optional approval to one of the target groups.
- The same update is approved for required approval to at least one of the other target groups that is at the same or greater depth in the target group tree.
For example, assume that you have a required approval on Update X for Group
A and an optional approval for Group B. If a computer belongs to both Group A and
Group B, the update would be listed as optional on the client computer. Because the target
groups are at the same level, required approval should always "win."

The WSUS 3.0 SP1 Update Package
3.0 SP1 is available on Windows Update. The package behavior is as follows:

Known issues with WSUS 3.0 SP1
- You receive an error message during the installation: "Failed to set SMTP_USERPASSWD property from SmtpUserPassword registry value (Error 0x800700EA: More data is available.)"
During the installation of this package, you may receive an error message that resembles the following in the %temp%\Wsussetup.log file:
Error MWUSSetup CUpgradeDriver::PerformPresetupActions: Failed to set SMTP_USERPASSWD property from SmtpUserPassword registry value (Error 0x800700EA: More data is available.)
This problem occurs because a Simple Mail Transfer Protocol (SMTP) password that is greater than 11 characters fails. This causes the WSUS 3.0 SP1 upgrade to fail. WSUS does not copy its local copy of the password.
To work around this issue, temporarily change the locally saved
password, run the WSUS 3.0 SP1 upgrade, and then change the password back to the original password that is used by the
SMTP account. To do this, follow these steps:
- Click Start, click
Administrative Tools, and then click Microsoft Windows
Update Server Services 3.0.
- Click to select Options, and then
click E-Mail notification.
- On the E-Mail Server tab, enter a
password that is less than 12 characters.
- Click OK to save the password.
Note Do not use Test because this password would be invalid for the SMTP
- Exit the WSUS Administration tool.
- Run the WSUS 3.0 SP1 upgrade.
- After you successfully upgrade to WSUS 3.0 SP1, change the password
back to the original password.
